My family calls it “comfort casserole” because it fills the kitchen with golden steam and settles into your bones. It’s simple, honest food: tender potatoes, savory ground beef, and oozy cheese that strings from plate to fork. Perfect for weeknights, potlucks, or any evening that needs a warm, reliable dinner.

Why This Recipe is Awesome
This bake hits all the cozy notes — creamy, cheesy, and meaty with just enough crisp edges to keep things interesting. It tastes like a mash-up of shepherd’s pie and scalloped potatoes, but way easier and with fewer pans. The textures play nicely: silky sliced potatoes, crumbly browned beef, and gooey cheddar that browns into crunchy, savory bits on top. It’s so forgiving even your oven can’t mess it up — and it makes the whole house smell like dinner success.
Ingredients
For the Main Dish:
- 2 lbs russet potatoes (about 4 medium), peeled and sliced 1/8–1/4 inch thick
- 1 lb lean ground beef (85% lean works well)
- 1 medium yellow onion, finely chopped
- 2 cloves garlic, minced
- 2 tbsp butter
- 2 tbsp all-purpose flour
- 1 1/2 cups milk (whole milk makes it richer; 2% works fine)
- 1/2 cup low-sodium beef broth
- 8 oz sharp cheddar cheese, grated (about 2 cups), plus extra for sprinkling
- 1 tsp kosher salt
- 1/2 tsp black pepper
- 1 tsp dried thyme or 1 tbsp fresh thyme leaves
- 1/2 tsp smoked paprika (optional, for warmth)
- Cooking spray or 1 tbsp oil for greasing the dish
- Fresh parsley or green onions, chopped for garnish
For the Sauce / Garnish (if applicable):
- Optional dollop of sour cream or a drizzle of hot sauce per plate
How I Make It
Step 1:
Preheat your oven to 375°F and grease a 9×13-inch baking dish with cooking spray or a little oil. While the oven warms, slice the potatoes thinly — the thinner they are, the quicker they become tender and the creamier the texture. Lay a damp towel over the slices so they don’t dry out as you work.
Step 2:
In a large skillet over medium-high heat, melt 2 tbsp butter with a splash of oil. Add the chopped onion and sauté until translucent and smelling sweet, about 4 minutes. Toss in the garlic for 30 seconds until fragrant. Add the ground beef, breaking it up with a spatula, and cook until nicely browned — you should hear a satisfying sizzle and see little caramelized bits forming. Season with salt, pepper, thyme, and smoked paprika.
Step 3:
Sprinkle the flour over the meat and stir to coat; cook 1 minute to lose the raw flour taste. Pour in 1 1/2 cups milk and 1/2 cup beef broth, stirring as the sauce thickens. Lower the heat and let it bubble gently into a creamy, gravy-like sauce — you’ll smell rich, savory notes and notice the sauce cling to the back of a spoon. Stir in 1 1/2 cups of grated cheddar until melted and glossy.
Step 4:
Layer half the potato slices in the prepared dish, overlapping slightly. Spoon half the beef-cheese mixture over the potatoes, spreading evenly. Repeat with the remaining potatoes and beef mixture. Cover tightly with foil and bake at 375°F for 35 minutes. Remove the foil, sprinkle the remaining cheese on top, and return to the oven uncovered for an additional 10–15 minutes until the cheese bubbles and the edges turn golden and crispy. You want fork-tender potatoes and a bubbling top — listen for that gentle sizzle when you open the oven.
Step 5:
Let the bake rest for 10 minutes before slicing — this helps the layers set so you get neat squares instead of a melty spill. Garnish with chopped parsley or green onions and serve with a spoonful of sour cream if you like. The buttered aroma and cheese strings make it impossible not to dig in.
Pro Tips
- Slice potatoes evenly using a mandoline or the side of a box grater plate. Even thickness ensures even cooking.
- If you want a lighter version, swap half the milk for unsalted chicken or vegetable broth — it thins the sauce but keeps flavor.
- Brown the beef well — those caramelized bits add deep, savory flavor you’ll notice in every bite.
- To speed up cooking, parboil the potato slices for 3–4 minutes, then drain and layer as directed.
Common Mistakes to Avoid
- Skipping preheating: Classic rookie move. It changes texture and bake time.
- Overmixing: Leads to dense or chewy results. Mix until just combined.
- Guessing cook time: Always use visual cues or a timer, not just vibes.
- Overcrowding pans: Give your food some breathing room to crisp properly.
Alternatives & Substitutions
- Use ground turkey or shredded rotisserie chicken instead of ground beef. Turkey gives a lighter flavor; chicken makes it milder — both still pair well with cheddar.
- Swap milk with half-and-half for a richer sauce, or use unsweetened almond milk for a lighter dairy alternative (the texture thins slightly).
- For a gluten-free version, replace the flour with 2 tbsp cornstarch mixed into the milk.
- Dairy-free option: use vegan butter and dairy-free shredded cheese; expect a slightly different melt and flavor but the same comforting vibes.
Variations & Tips
- Spicy: add 1–2 tsp chipotle in adobo or a diced jalapeño to the beef mixture for heat.
- Kid-friendly: stir in a handful of frozen corn or peas to sneak veggies in without fuss.
- Vegetarian: swap beef for cooked lentils or crumbled tempeh seasoned the same way.
- Herby twist: stir in 1 tbsp chopped fresh rosemary for piney, aromatic notes.
- Make it extra-cheesy: fold half the cheese into the sauce and shred a different cheese (Monterey Jack) on top for melty layers.
- Creative twist: add a layer of caramelized onions between the potatoes and beef for sweet-savory depth.
FAQ (Frequently Asked Questions)
- Can I make this ahead of time?
- Yes! Assemble the bake up to the point of baking, cover tightly, and refrigerate for up to 24 hours. Remove from the fridge for 30 minutes before baking and add a few extra minutes to the cook time until bubbly.
- Can I double the recipe?
- Sure thing. Use a 9×13 plus an additional 9×13 or a 11×15 pan. Bake times may increase slightly — check for bubbling cheese and tender potatoes; add 10–15 minutes if needed.
- Can I substitute butter with oil?
- Technically yes, but you’ll miss that buttery magic. Use ¾ the amount of oil (so 1 1/2 tbsp) and consider adding a pat of butter on top before baking for flavor.
- How do I know it’s done?
- Look for bubbling sauce at the edges, a golden-brown cheesy top, and fork-tender potato slices. If a knife slides through the center without resistance, it’s ready.
- What if I don’t have ingredient X?
- No panic — swap onion for 1 tsp onion powder plus a chopped shallot, or use any sturdy melting cheese (Colby, Monterey Jack) if you’re out of cheddar.
How I Like to Serve It
I love scooping this bake onto warm plates with a crisp green salad or roasted Brussels sprouts on the side. For easy weeknight dinners, I pair it with steamed green beans and a cold beer; for potlucks, I bring extra napkins and a big spoon because it disappears fast. It works all year — comforting in winter, satisfying for cool summer nights around a patio fire.
Notes
- Store leftovers in an airtight container in the fridge for up to 3 days. Reheat individual slices in the oven at 350°F until warmed through, about 15–20 minutes, or microwave for quick lunches.
- Ground beef safe cooking temp: cook to an internal temperature of 160°F.
