This isn’t a weeknight throw-together. It’s a smothered pork chop and scalloped potato casserole that builds flavor from the ground up, seared pork crust, a from-scratch cream sauce, and potatoes that turn tender without going soggy.
The trick is getting the pork to stay juicy through a long bake, and the answer is a hard sear before it ever hits the oven. That crust does double duty: it locks in moisture and leaves browned bits in the pan that make the sauce taste meaty.
The whole thing bakes in one skillet, so the potatoes soak up that porky cream while the chops ride on top, their seared crust staying intact. It’s the kind of layered dish where every component earns its place.
I once ended up with a pool of greasy liquid at the bottom of the casserole, the cheese floating on top like an oil slick.
Searing locks in flavor and texture
A quick sear gives pork chops a browned crust that adds savory depth. That browning also seals the surface, so the chops stay juicy through the long bake.
Plus, the browned bits left in the skillet, the fond, dissolve into the sauce, giving it a meaty backbone you can’t get any other way. Without searing, the chops would steam in the oven and turn out pale and dry.
A creamy sauce that won’t break or get gluey
The sauce starts with a butter-flour roux cooked until bubbly and nutty-smelling; that’s your cue it’s ready. When you whisk in milk and broth, the flour already thickened, so the sauce coats the potatoes without becoming pasty. Heavy cream adds richness and keeps the sauce from curdling under heat.
Layering the potatoes and sauce in the pan lets each slice absorb liquid evenly, so the casserole holds together when scooped. Now I make sure to cook the flour-butter paste fully until it’s bubbly and smells nutty before slowly whisking in the milk and broth. That step is the difference between a silky sauce and one that tastes raw.
Why Yukon Gold or Russet potatoes work best
Yukon Golds hold their shape during baking but turn creamy, while Russets are starchier and soak up the sauce like a sponge, making the casserole tender. Both slice evenly and cook through in the 65-minute bake. Waxy potatoes like reds stay too firm or can turn slippery, so stick with these for the right texture.

What to look for when buying for this casserole
Pork Chops: Bone-in chops stay juicier during the long bake, but boneless work fine if you prefer easy eating.
Yukon Gold or Russet Potatoes: Yukon Golds stay creamy and hold shape; Russets soak up sauce and turn tender. Slice them 1/8 inch thick.
Shredded Mozzarella or Gruyère Cheese: Buy a block and shred it yourself. Pre-shredded cheese has anti-caking agents that make the sauce grainy.
Heavy Cream: Heavy cream gives the sauce richness and stability. Half and half works but the sauce will be thinner.
Browning the pork chops and building the sauce
Season and sear the chops
Rub the chops with salt, pepper, garlic powder, onion powder, and paprika. Heat oil in the skillet until it shimmers.
Sear the chops 2 to 3 minutes per side until deeply browned. The fond left behind is your flavor base.
Cook the onions and garlic
Reduce heat to medium, melt butter, and add sliced onions. Stir occasionally until they turn golden and soft, about 5 minutes. Add garlic and cook until fragrant, about 1 minute.
The onions should be translucent with brown edges.
Make the roux and sauce
Whisk in flour and cook 1 to 2 minutes until the mixture is bubbly and smells nutty. Slowly whisk in milk, broth, and cream. Add thyme.
Bring to a simmer and stir until the sauce thickens enough to coat a spoon.
Layer potatoes and sauce
Spread half the sliced potatoes in the skillet. Pour half the sauce over them, then sprinkle half the cheese. Repeat with remaining potatoes, sauce, and cheese.
The potatoes should be nearly submerged; press them down if needed.
Bake covered, then uncovered
Tuck the seared chops on top. Cover with foil and bake at 375°F for 45 minutes. Remove foil and bake 20 to 25 minutes more.
The potatoes are done when a knife slides through with little resistance and the top is golden brown.
Rest before serving
Let the casserole rest 10 minutes out of the oven. This lets the sauce set so slices hold together.
Garnish with parsley if you like. The layers should be distinct but cohesive.

Instructions
Preheat Oven:
Preheat oven to 375°F (190°C).Season Pork Chops:
Generously rub the pork chops with salt, pepper, garlic powder, onion powder, and paprika.Sear Pork Chops:
Heat olive oil in an oven-safe skillet over medium-high heat. Sear pork chops for 2-3 minutes per side until browned. Remove and set aside.Caramelize Onions:
In the same skillet, melt butter over medium heat. Add sliced onions and cook for about 5 minutes until caramelized. Add fresh garlic and sauté for 1 minute.Make Sauce:
Whisk in flour and cook for 1-2 minutes. Gradually whisk in milk, chicken broth, and heavy cream. Add thyme. Bring to a simmer, stirring until thickened.Layer Potatoes and Sauce:
Layer half of the sliced potatoes in the skillet. Pour half of the sauce over the potatoes. Sprinkle half of the cheese.Repeat Layering:
Repeat layering with remaining potatoes, sauce, and cheese.Add Pork Chops:
Nestle the seared pork chops on top of the potato mixture. Cover the skillet with foil.Bake Covered:
Bake for 45 minutes. Remove foil and bake for an additional 20-25 minutes until potatoes are tender and top is golden.Rest and Garnish:
Let rest for 10 minutes before serving. Garnish with fresh parsley if desired.
Storage and Serving
This casserole is best served fresh, right after the 10 minute rest. The potatoes are tender, the sauce is creamy, and the pork chops are juicy.
Leftovers will keep in the fridge for up to 3 days, but the texture shifts: the potatoes continue to absorb the sauce, making them softer and the casserole creamier. To reheat, cover with foil and warm in a 350°F oven for 15 20 minutes, or microwave individual portions in 30 second bursts. The pork chops may dry out slightly, so add a splash of milk or broth before reheating.
Freezing is not recommended; the dairy based sauce can separate and the potatoes become grainy upon thawing. Make ahead: you can assemble the casserole (without the final 20 minute uncovered bake) up to 24 hours in advance.
Refrigerate covered, then add 10 minutes to the covered bake time. Garnish with fresh parsley just before serving, not during storage. For the best texture, eat within 2 hours of baking.
What you can swap (and what to leave alone) in this casserole
Cheese: Gruyère for mozzarella, or sharp cheddar for either. Gruyère melts smooth and adds nuttiness; cheddar gives a sharper, more pronounced cheese flavor.
Both work because the sauce is rich enough to carry the swap. Pre-shredded cheese will make the sauce grainy, so shred from a block.
Milk: Skim or unsweetened almond milk for whole milk. The sauce will be thinner and less creamy, but it still thickens from the roux.
Skim milk may curdle slightly if the heat spikes, so keep the simmer gentle. Almond milk works but adds a faint nutty note. Stick with whole milk if you want the richest texture.
Potatoes: Russet for Yukon Gold or vice versa. Russets absorb more sauce and turn softer, almost mashed inside. Yukon Golds hold their shape better and stay creamy.
Slice both 1/8 inch thick. Waxy potatoes like reds stay too firm and don’t soften enough in the bake, skip those.
Flour: Gluten-free all-purpose flour blend for all-purpose flour. Use a blend with xanthan gum (like Bob’s Red Mill 1-to-1). The roux will thicken similarly, but the sauce may be slightly less smooth.
Cook the roux until bubbly and nutty just like with wheat flour. Do not skip the roux, it’s essential for thickening.
Tips
- Slice the potatoes 1/8 inch thick using a mandoline or sharp knife. Thicker slices will not soften enough in the 65-minute bake, leaving hard layers in the casserole.
- Tuck the pork chops into the potato mixture so they are partially submerged. This keeps them moist during the long bake and prevents the exposed tops from drying out.
