Creamy, savory baked potato filling with buttery herbs and soft bread, a hearty Pennsylvania Dutch Thanksgiving side with German roots, perfect alongside roasted turkey.

Ingredients

Russet potatoes 900 grams (about 4 medium, peeled, cut into 1-inch cubes)
Unsalted butter 113 grams (1 stick, divided)
Yellow onion 150 grams (1 medium, finely diced)
Celery 100 grams (2 stalks, finely diced)
Garlic 9 grams (3 cloves, minced)
Day-old white bread 120 grams (4 slices, cut into ½-inch cubes)
Whole milk 180 ml (¾ cup)
Low-sodium chicken broth 120 ml (½ cup)
Cold water 2 liters (for boiling potatoes)
Dried sage 1 teaspoon (1 gram)
Dried thyme ½ teaspoon (0.5 grams)
Kosher salt 1 tablespoon (18 grams, divided)
Ground black pepper ½ teaspoon (1 gram)
Fresh flat-leaf parsley 6 grams (2 tablespoons, chopped, divided)
Large egg 50 grams (1, lightly beaten)

Steps

1

Cook the potatoes

Place 900g peeled, 1-inch cubed russet potatoes in a large stockpot, cover with 2 liters of cold water mixed with 9g (1.5 tsp) kosher salt, bring to a rolling boil over medium-high heat, then reduce to medium heat to maintain a gentle simmer. Cook for 12-15 minutes until fork-tender, when a paring knife slides through a potato cube with no resistance. Drain fully in a colander and set aside.

step1:Cook the potatoes
2

Sauté aromatic vegetables

Heat 80g (≈5.5 tbsp) unsalted butter in a 10-inch skillet over medium heat. Once the butter melts and foaming subsides, add 150g finely diced yellow onion and 100g finely diced celery. Cook for 7-8 minutes, stirring occasionally with a wooden spoon, until vegetables are soft and translucent. Add 9g minced garlic, 1g dried sage, and 0.5g dried thyme, stir constantly for 30 seconds until fragrant (do not let garlic burn), then remove the pan from heat.

Combine filling base

Transfer the drained cooked potatoes to a 3-liter large mixing bowl, add the sautéed aromatic butter and vegetable mixture, 180ml whole milk, 120ml low-sodium chicken broth, 50g lightly beaten large egg, remaining 9g (1.5 tsp) kosher salt, and 1g ground black pepper. Mash with a potato masher until mostly smooth, leaving a few small soft potato chunks for texture. Fold in 120g ½-inch cubed day-old white bread and 4g chopped fresh parsley until all ingredients are evenly distributed.

4

Assemble baking dish

Preheat your oven to 190°C (375°F). Use 5g (1 tsp) of the remaining unsalted butter to grease the bottom and sides of a 23x23cm (9x9 inch) square baking dish evenly. Scoop the entire potato filling mixture into the prepared dish, spreading it into a smooth, even layer with a silicone spatula.

Step 4
step4:Assemble baking dish
5

Bake until golden

Melt the remaining 28g (2 tbsp) unsalted butter, then drizzle it evenly over the top of the unbaked filling. Place the dish on the middle rack of the preheated oven, bake uncovered for 30-35 minutes, until the top is lightly golden brown and the edges are actively bubbling. Remove from the oven, let the filling rest for 5 minutes at room temperature, then garnish with the remaining 2g chopped fresh parsley before serving.

Step 5
step5:Bake until golden

Tips

1.Use day-old (slightly stale) white bread instead of fresh bread for this recipe: fresh bread will turn mushy and make the filling soggy, while stale bread holds its shape and absorbs savory butter and herb flavors beautifully.
2.This dish is very make-ahead friendly: assemble the unbaked filling in the greased dish, cover tightly with plastic wrap, and refrigerate for up to 24 hours. Add 10 minutes to the baking time when cooking straight from the refrigerator.
3.Customize the filling to your taste: swap chicken broth for vegetable broth to make it vegetarian, add 60g crumbled cooked breakfast sausage for extra savoriness, or top with 30g toasted breadcrumbs for a crunchier top.

Potato Filling:Frequently Asked Questions

1.How is this classic baked potato filling different from regular mashed potatoes?
Great question! Unlike smooth, dairy-forward mashed potatoes that are often light on mix-ins, this Pennsylvania Dutch staple with deep German roots incorporates butter-soaked soft bread and sautéed aromatics for a heartier, textured, savory bite that’s perfectly designed to soak up roasted turkey gravy at Thanksgiving and other holiday meals.
2.Can I use a potato variety other than Russets for this recipe?
I strongly recommend sticking with Russet potatoes for the best results. Their high starch content breaks down into that signature fluffy, light base when cooked; waxy options like red potatoes or Yukon Golds will turn dense, gummy, and overly firm, throwing off the filling’s classic soft, creamy, melt-in-your-mouth consistency.
3.Do I have to bake the potatoes first, or can I boil them to save prep time?
Baking whole, pricked Russets at 400°F for about an hour delivers the best deep, earthy, dry fluffy texture, but if you’re crunched for time on a holiday, you can cube and boil them for 12–15 minutes until fork-tender. Just drain them extremely well first—excess water will make your filling soggy instead of rich and creamy.
4.What type of bread works best for the soft bread component in this filling?
Plain, soft white sandwich bread is the traditional, most reliable pick for this recipe. Tear it into 1-inch pieces (remove crusts for an ultra-smooth texture) so it absorbs melted butter and potato starch evenly. Skip crusty sourdough or dense whole-grain loaves, which create tough, chewy bits in the final dish.
5.Can I make this baked potato filling a day ahead to cut down on Thanksgiving day work?
Absolutely! Assemble the filling fully, transfer it to a greased, buttered baking dish, let it cool completely to room temperature, then cover tightly with foil and refrigerate for up to 24 hours. When ready to serve, bake covered at 375°F for 30 minutes, then uncover for 10 minutes to crisp the top slightly.
6.My filling turned out too dry when I tested the recipe—how do I fix that?
Dry filling usually happens if potatoes were over-drained, your bread was overly stale, or you skimped on melted butter during prep. Fix it immediately by stirring in 2 tablespoons of warm low-sodium chicken broth or melted butter at a time, mixing gently, until you reach that soft, creamy, spreadable consistency. Don’t overmix, or it will turn gummy!
7.How can I add extra flavor to the filling without making it too heavy?
Stir in 1 teaspoon of dried rubbed sage or 2 tablespoons of chopped fresh parsley and thyme right before baking for a bright herby kick, or add ¼ cup of finely chopped cooked bacon for salty, smoky depth. Skip heavy mix-ins like loads of cheddar or sour cream, which weigh down the filling’s light, classic texture.
8.Do I need to sauté the onion, celery, and garlic first, or can I mix them in raw?
Always sauté those aromatics first in melted butter over medium-low heat for 5–7 minutes, until the onion is soft and translucent and the garlic is fragrant (don’t let the garlic burn!). Raw veggies will stay crunchy and release harsh, sharp flavors as the filling bakes, ruining the dish’s signature mellow, savory profile.
9.What main dishes pair well with this filling besides roasted Thanksgiving turkey?
While it’s a natural match for roasted Thanksgiving turkey, this hearty side also pairs beautifully with baked glazed ham, whole roast chicken, pan-seared pork chops, or braised bratwurst for cozy cold-weather weeknight meals. Serve it with tangy green beans or pickled beets to cut through the richness, just like traditional PA Dutch spreads do.
10.Can I adapt this recipe to be dairy-free for guests with dietary restrictions?
Yes, this is a really easy recipe to adapt for dairy-free guests! Swap the unsalted butter for a high-quality neutral plant-based butter (skip olive oil, which will alter the classic buttery flavor), use soft dairy-free white bread, and confirm any broth you use for moisture adjustments is also dairy-free for full compliance.

OMG this classic baked potato filling is a total game changer for our weekly family dinner nights! I added a little extra shredded cheddar and crumbled bacon on top before popping it back in the oven for 5 minutes, and my husband and three kids practically licked their plates clean. So easy to throw together even on chaotic school nights, 10/10.

I did the exact same extra cheddar and bacon trick for my neighborhood potluck last weekend and people were begging me for the recipe! Nobody could believe how simple it was.

Love that cheddar and bacon add-in! So glad it was a hit with your family — those little custom twists are what make this recipe so versatile for any occasion.

This filling is perfect for Sunday meal prep! I made a big batch on Sunday, stuffed it back into the potato skins, wrapped them individually, and grabbed one for lunch every day this week. Held up perfectly in the fridge, reheats like a dream in the air fryer. Only note is I wish I’d added a little more sour cream next time for extra creaminess.

Great call using this for meal prep! If you love extra creaminess, try stirring in an extra 2 tbsp of full-fat sour cream or a splash of heavy cream when mixing the filling — it makes it so luxe.

First recipe I’ve tried in my new apartment that didn’t turn out a total disaster lmao. Super straightforward, didn’t require any fancy tools, and tasted exactly like the loaded baked potatoes I get at the campus sports bar. Saved this to my rotation for sure!

yesterday

Made this for my kids’ post-soccer practice dinner last night and all three of them asked for seconds, which never happens. I used the leftover filling to make little potato skin appetizers for my buddy who came over to watch the game later, and he raved about them too. SO good, way better than the sad frozen stuffed potatoes I used to buy.

Wait the frozen ones are such a letdown, right?! I’m gonna try the leftover filling trick for my son’s football watch party this weekend, sounds perfect.

Pro tip: add a dash of smoked paprika to the filling, it takes the flavor up like 3 notches without any extra work.

I was worried this would be too bland since it’s a “classic” recipe, but the balance of butter, chives, salt, and pepper is absolutely perfect. I served these alongside grilled steak for my date night in, and my date thought I spent way more time on them than I actually did. Win win!

Ooh serving with steak is such a good call! I always make these with fried chicken but steak sounds way more fancy for date night, stealing that idea.

Made this vegan by swapping the butter for plant-based butter, using vegan sour cream, and adding some roasted broccoli bits into the filling. It came out so creamy and flavorful, even my omnivore roommate stole a bite and said it was amazing. Great base recipe to customize however you want!

Wait, 55 minutes total cook time? I thought baked potatoes took forever, but this was so quick on a weeknight. Wait no — hold on, did I do something wrong? My potatoes were still a little hard in the middle when I pulled them out to scoop the filling after 45 minutes of baking? Maybe my oven runs cool? Still tasted great once I popped them back in for 10 more minutes though.

3 days ago

My oven runs super cool too! I always add 10 extra minutes to any baked potato recipe now, no more crunchy middles.

3 days ago

Oven temperature can vary so much from model to model, so adding that extra bake time when needed is exactly the right call! Next time you can poke the potatoes with a fork before baking to help them cook a little faster too.

I brought these to our church potluck last Sunday and the pan was completely empty by the time everyone went through the line. Multiple people came up to ask for the recipe, which always makes me feel like a winner. I topped half with bacon bits and half with chopped chives for the vegetarians in the group, which worked out perfectly.

That makes us so happy to hear! Offering both bacon-topped and veggie-friendly versions is such a thoughtful move for group meals — we’re definitely stealing that tip for our next potluck.

As someone who can barely boil water without messing it up, this recipe was so easy to follow. The steps were super clear, no weird ingredients I had to run to three different grocery stores to find, and the end result tasted like something from a restaurant. Can’t wait to make it again for my parents when they visit next weekend!

This is exactly the classic baked potato filling I grew up eating at my grandma’s house! I was worried I’d never be able to replicate that fluffy, buttery, perfectly salty flavor, but this recipe nailed it. I got a little emotional taking the first bite, it tasted just like childhood.

Right?! I’ve been searching for a recipe that tastes like my grandma’s stuffed potatoes for years, can’t wait to try this this weekend. Fingers crossed it hits the same nostalgia spot for me!

Great base recipe! I stirred in a handful of pickled jalapeños and a sprinkle of pepper jack cheese into the filling for a little kick, and it was chef’s kiss. Perfect balance of creamy, salty, and spicy. My only complaint is I made way too little, my roommates ate half of it before I even got to sit down for dinner.

30 minutes ago

Pickled jalapeños in baked potato filling?! Why have I never thought of that? That sounds like the perfect upgrade, I’m adding that to my grocery list for tonight.

The pickled jalapeño and pepper jack twist sounds incredible! We love when people add their own favorite flavors to make the recipe their own — we might have to test that version ourselves soon.
