intro

An iconic Door County, Wisconsin tradition of flaky boiled whitefish, tender potatoes, and sweet corn, cooked outdoors for casual, communal summer gatherings.

Ingredients

Lake Michigan whitefish steaks (bone-in, skin-on, 10cm thick) 900 grams (2 lbs)
Small red new potatoes (scrubbed, unpeeled) 680 grams (1.5 lbs, ~2cm diameter)
Yellow onion (peeled, quartered through root end) 340 grams (2 medium)
Sweet corn on the cob (husked, cut into 5cm rounds) 450 grams (4 medium ears)
Kosher salt 120 grams (1/2 cup)
Whole black peppercorns 6 grams (1 tablespoon)
Dried bay leaves 3 leaves
Unsalted butter (melted, for serving) 113 grams (1/2 cup / 1 stick)
Fresh lemon (cut into wedges, for serving) 120 grams (2 medium)

Steps

1

Prepare Boil Pot and Burner

Set up a 20-liter (5-gallon) outdoor propane stock pot burner on a flat, heat-safe surface at least 1 meter away from flammable materials like deck railings or dry grass. Fill the pot with 16 liters (17 quarts) of cold water, add the 120g kosher salt, 6g black peppercorns, and 3 bay leaves, then cover and bring to a rolling boil over high heat (12-15 minutes).

2

Add Red New Potatoes

Once the water reaches a full, vigorous rolling boil, carefully add the 680g whole unpeeled red new potatoes to the pot. Maintain a steady medium-high boil, leave the pot uncovered, and cook for 12 minutes until potatoes are almost tender when pierced with a fork (they will have a slight firm, starchy center at this stage).

step2:Add Red New Potatoes
3

Add Onions and Corn

After the potatoes have cooked for exactly 12 minutes, add the 340g quartered yellow onions and 450g cut corn sections to the boiling pot. Stir gently once with a long-handled slotted spoon to submerge all vegetables, keep the water at a steady medium-high boil, and cook uncovered for 4 minutes to slightly soften the onions and corn.

Step 3
step3:Add Onions and Corn
4

Add Whitefish Steaks

Gently lower the 900g whitefish steaks into the boiling pot in a single even layer, ensuring all pieces are fully submerged (add 250ml extra hot water if needed to cover). Return the water to a gentle medium boil (adjust heat down slightly if it gets too vigorous), then set a timer for 8 minutes, cooking uncovered until the fish flakes easily with a fork and reaches an internal temperature of 63°C (145°F).

Step 4
step4:Add Whitefish Steaks
5

Heat to Boil Over

Once the 8-minute fish cook time is up, turn the propane burner to its highest heat setting for 60-90 seconds, until the boiling water foams with white scum and rises 5-7cm above the pot rim, spilling over the sides to carry away excess fish oil and impurities. Immediately turn the burner completely off once the controlled boilover happens.

6

Remove and Drain Ingredients

If your pot has a fitted inner strainer basket, lift it out and let all food drain for 30 seconds over the pot; if not, remove all ingredients with a long slotted spoon, shaking off excess water. Arrange the drained fish, potatoes, onions, and corn on a large communal wooden platter lined with paper towels, drizzle evenly with the 113g melted unsalted butter, and serve immediately with lemon wedges on the side.

Tips

1.Do not reduce the salt amount in the boiling water: the heavily salted (seawater-strength) brine seasons the ingredients evenly and keeps the fish firm instead of mushy during the vigorous boil.
2.Skip the traditional kerosene-fueled boilover for home cooking: cranking the burner to maximum heat as directed creates a safe, controlled overflow that removes fish scum without the fire risk of adding fuel to an open flame.
3.Always use bone-in, skin-on whitefish steaks cut at least 2.5cm thick: thin, boneless, skinless fillets will break apart and turn mushy in the rolling boil, while bone-in steaks hold their shape and have richer flavor.

Fish Boil (Wisconsin):Frequently Asked Questions

1.Why do you recommend bone-in, skin-on Lake Michigan whitefish steaks instead of boneless fillets?
Bone-in, skin-on steaks hold up perfectly to the vigorous rolling boil without falling apart, and the bone and skin infuse both the cooking water and fish with rich, briny depth you can’t get from thin boneless fillets. They also stay juicier through the short cook time, delivering that classic flaky, moist texture Door County boils are famous for.
2.Do I really need to use as much kosher salt as traditional recipes call for in the boil water?
Yes! Aim for water as salty as seawater (roughly 1 cup kosher salt per 4 gallons of water) to season potatoes, corn, and fish evenly from the inside out as they cook. The salt also raises the boiling point slightly for more even cooking, and cuts through the fish’s mild richness so no bite tastes flat or bland.
3.Does the order I add ingredients to the pot actually matter, and what order should I use?
Order absolutely matters to avoid mushy veggies or rubbery overcooked fish! Add dense unpeeled red new potatoes first, since they take longest to cook, drop in quartered onions 10 minutes later, add corn rounds 5 minutes after onions, then finish with whitefish steaks for the last 6 to 8 minutes for perfectly tender results across every component.
4.I don’t live near Lake Michigan—what’s a good substitute for the traditional whitefish?
If you can’t source fresh Lake Michigan whitefish, opt for other thick, firm, mild white fish steaks as a close swap: Great Lakes lake trout, thick-cut cod steaks, or haddock steaks all work beautifully. Skip thin, delicate options like tilapia or sole, which will fall apart in the rolling boil and lack the recipe’s signature meaty, satisfying texture.
5.What’s the dramatic boil-over trick I’ve heard about at classic Door County fish boils?
That iconic boil-over happens when cooks spike the fire’s heat suddenly to make starchy, fishy surface foam spill over the pot rim, skimming off impurities and excess fish oil for a cleaner flavor. Local spots often use a small splash of kerosene for the heat spike, but home cooks can safely use a glug of neutral oil to get the same effect without fumes.
6.How do I tell when the whitefish is perfectly cooked, not tough and overdone?
Pull the fish as soon as it turns fully opaque and flaks easily when you nudge its thickest point with a fork, usually 6 to 8 minutes after adding it to the rolling boil. It cooks extremely fast at a constant hard boil—overcooking even by 2 minutes will leave fish dry and rubbery, so set a timer and don’t step away once steaks go in.
7.Can I prep ingredients ahead of time for a big backyard communal gathering?
Absolutely! You can scrub the unpeeled new potatoes, husk and cut corn into rounds, peel and quarter onions, and pat fish steaks dry up to 1 day ahead. Store each prepped ingredient in separate sealed containers in the fridge, then pull them out 20 minutes before boil time to take the chill off so they cook evenly.
8.What traditional sides are served alongside the boiled fish, potatoes, and corn?
Classic Door County fish boils skip fussy extras: serve the drained, hot components with drawn melted butter for dipping, lemon wedges, a light sprinkle of parsley, tangy creamy coleslaw, and crusty rye bread. Many local spots also add dill pickles as a briny, sharp contrast to the mild, rich spread.
9.What equipment do I actually need to make this at home, and can I cook it indoors?
For an 8-serving batch, use a 10–12 gallon tall stockpot with a perforated basket insert to easily lift cooked food out, plus a sturdy outdoor propane burner. This recipe produces too much steam and heat for indoor stovetops, and the tall pot sides will contain the rolling boil until you do the intentional boil-over step.

OMG, this was such a hit at our extended family dinner last weekend! I grew up going to Door County every summer as a kid and I’ve been chasing that perfect fish boil taste for years, and this recipe nailed it. My kids even went back for seconds, which never happens with white fish! The only swap I made was using red potatoes instead of yellow because that’s what I had in the pantry. 10/10, will be making this for our Labor Day potluck for sure!

So glad you loved it! Red potatoes work great in this, I do that swap all the time when I’m making it for a big crowd too. Pro tip: toss a little extra melted butter on top right before serving and it tastes exactly like the boils you get at the old supper clubs up there.

That’s such a great swap! Red potatoes hold up beautifully to the boil, and that extra melted butter tip from @DoorCountyLocal920 is chef’s kiss. So happy this brought back those summer Door County memories for you!

Really solid recipe, cooked this up on my outdoor burner for the guys during our football watch party. The flavor was spot on, though I will say I overcooked the fish the first go-round because I misjudged how fast it cooks in that boiling pot. Next time I’ll set a timer like the recipe says instead of guessing! Would’ve been a 5 if I didn’t mess up the fish texture, but everyone raved about the potatoes and onions regardless.

So glad the crew enjoyed it! Fish can go from perfectly flaky to overcooked in literally 2 minutes with this high-heat boil, so that timer is non-negotiable for sure. Next time you make it, pull the pot the second the fish starts to flake easily with a fork and it’ll turn out perfect!

Game changer! I’ve been looking for a fun, interactive dinner to make when we have friends up to our cabin, and this was perfect. Everyone gathered around the pot while it cooked, told stories, and we ate off paper plates with tons of lemon wedges and coleslaw on the side. Felt like a proper summer feast without a ton of fancy prep. SO good.

Tasted good, but man, medium difficulty is no joke! I made a huge mess on my stovetop when the water boiled over, and I swear my whole apartment smelled like fish for two days after. Maybe this is better for people with outdoor cooking setups? I followed the directions exactly, but my stovetop just couldn’t handle the big pot needed for all the ingredients. Probably won’t make it again in my tiny apartment, but I’d eat it if someone else made it!

3 days ago

Oh I feel this! I did this on my tiny apartment stove too, I just split the ingredients between two smaller pots instead of using one giant stock pot and didn’t have any boil over issues. Cracking a window and running the range hood the whole time helped with the fish smell too!

Great tip from @ApartmentChefMia! Splitting between two pots works perfectly for smaller kitchen setups, and this recipe is absolutely doable indoors with a little ventilation. Sorry to hear about the stovetop mess, that high boil can definitely get unruly if you don’t keep a close eye on it at first!

Brought this to our neighborhood block party and people were lined up for seconds! I was worried the fish would be too bland for our Southern crowd, but that seasoned boil and the butter drizzle had everyone asking for the recipe. I served it with hushpuppies and tartar sauce on the side, which was the perfect pairing. Already got three texts this morning asking when I’m making it again!

The hushpuppy side is genius! I made this last month and did coleslaw but I’m definitely adding hushpuppies next time, that’s such a good match for the buttery fish and potatoes.

Took my grandkids fishing last week and caught a mess of whitefish, so I looked up a fish boil recipe to use it up. This took me right back to the fish boils I went to when I was stationed up near Door County in the Army. Tasted exactly like I remembered, and the grandkids thought it was the coolest thing ever to watch the pot boil over like that (we did it outside on the turkey fryer, thank goodness). Saved this recipe to my old recipe box, will be a family staple from now on.

Made this for my Sunday meal prep, and it reheats way better than I thought it would! I portioned it out into containers with a side of roasted broccoli, and it made 6 full servings for my work lunches this week. The only reason I’m not giving it 5 stars is I wish the recipe had a note about how long it keeps in the fridge — I guessed 4 days and so far it’s holding up great!

5 minutes ago

So glad this worked for your meal prep! Stored in an airtight container, the leftovers will keep for 3-4 days in the fridge, which makes it perfect for quick weeknight lunches. I’ll add that note to the recipe card right now — thanks for the great feedback!

I’ve been to actual Door County fish boils a half dozen times, and I was skeptical a home recipe could live up to the real deal. Let me tell you — this is spot on. The boil time for the potatoes was exactly right, the fish was flaky and not overdone, and even the traditional boil over trick worked when I tossed the last bit of butter in (pro tip: stand back when you do that if you’re on an outdoor burner, I splattered butter on my hoodie lmao). 10/10, no notes.

30 minutes ago

Wait you did the boil over thing on an outdoor burner? I’ve been too scared to try that part on my deck, did it make a huge mess? I’ve got a turkey fryer I’ve been meaning to use for this, I just don’t want to scrub butter and potato starch off my patio for an hour.

So happy this recipe is naturally gluten free! I’ve been looking for fun weekend dinners I can make for my whole family without having to swap a million ingredients for my celiac kid, and this was perfect. No weird hidden gluten, just simple, hearty food that everyone devoured. We did ours outside on the propane burner and it was such a fun Friday night activity, even the dog hung around waiting for scraps. Will absolutely be making this again all summer long.
