After one of those long days—you know, the kind where you’re running on coffee and crossed fingers, chasing deadlines at work, and practically mauling the snack cabinet because dinner feels impossibly far away—the question of “what to make tonight?” can send anyone over the edge. Around here, comfort food is my secret weapon, and casseroles are my soft landing. There’s just something about a big, bubbling dish on the table that makes me breathe easier and exhale, “Ahhh, home.”
If you haven’t tried it yet, this five-ingredient hamburger and potato casserole is basically the definition of a weeknight hero. It pulls together with pantry staples, tastes like your favorite childhood meal, and (bonus!) nobody ever guesses how simple it really is. I brought this to a neighbor’s potluck last spring, and I’m not exaggerating—folks kept circling back for “one more spoonful,” until the pan was gleaming clean. If that’s not a sign of a keeper, what is?

Ingredient Notes & Casual Tips
1 lb lean ground beef: I usually go for 80/20 since there’s enough fat for flavor but not so much that it turns greasy. If you’re feeling virtuous, ground turkey or even chicken works (just add a splash of oil so it doesn’t dry out). I’ve even used a plant-based crumble for Meatless Mondays, and nobody grumbled!
4 large potatoes, thinly sliced: Yukon Golds are my go-to for that rich, creamy vibe, but russets give you that classic, fluffy feel. Don’t sweat it—any potato will do, and nobody’s grading your slicing skills (mandoline if you’re brave, a sharp knife if you’re like me and prefer keeping your fingerprints intact). Thinner is better for fast, even cooking—seriously, a few millimeters makes a difference.
1 (10.75 oz) can condensed cream of mushroom soup: Old-school, yes, but it ties everything together with that classic casserole flavor. Cream of chicken or celery works if mushrooms aren’t your thing. Plant-based “cream of” soups have come a long way, so go wild if you want a dairy-free option.
½ cup milk: Just to thin out the soup—any kind of milk you’ve got hiding in the fridge will work (even oat or almond in a pinch). I once used leftover half & half and felt like a total rebel, but it came out extra luxurious.
1 cup shredded cheddar cheese: You want ooey-gooey. I use sharp cheddar for more flavor, but truly, whatever’s in your cheese drawer (Monterey Jack, Colby, even a handful of pre-shredded “Mexican blend”) is fair game. If you accidentally go heavy-handed—no judgment!
Salt and pepper, to taste: Trust me, the right seasoning changes everything. Season the beef as it browns and give the potatoes a dash too. Extra herbs are always welcome—paprika, garlic powder, or Italian seasoning if you’re feeling a little “chef-y.”
Directions
- Preheat your oven to 350°F and grease a 9×13-inch baking dish. Seriously, don’t skip greasing—even a quick olive oil swipe makes sure those cheesy edges release easily. And those edges? Kinda the best part.
- Brown the beef. Toss your ground beef into a skillet over medium heat, crumble it up, and cook until it’s no longer pink—usually 5 to 7 minutes. Season well with salt and pepper. Drain off most of the fat (unless you used very lean meat, then you’re good).
- Layer the potatoes. Spread your potato slices into a single, overlapping layer on the bottom of your prepared dish. This makes a sturdy base and keeps the beef snug up top. (This is the part where you can take a deep breath and just let imperfect potato slices do their thing—rustic is pretty!)
- Mix the sauce. In a small bowl, mix together the cream of mushroom soup and milk until smooth. No need to break out the mixer—a fork or whisk is just fine.
- Assemble the casserole. Scatter the cooked, drained beef over the potatoes. Pour that silky soup mixture evenly across the top and give your dish a little shimmy so it works into every nook and cranny. Smooth it out if you need to, especially around the corners—the potatoes will thank you later.
- Bake and check for doneness. Slide it into the oven (uncovered!) and set your timer for 60 minutes. After an hour, poke a fork in the center to test the potatoes—if they’re tender, you’re golden; if not, let it go for another five or ten minutes. Every oven is a little quirky, so don’t stress.
- Add the cheese topping. Sprinkle your cheddar over the top (more is more, right?). Pop the dish back in the oven for another 15 minutes, until the cheese is all bubbly, melty, and you see those little golden patches starting to appear. Sometimes I’ll pop the broiler on for just a minute or two to get the cheese extra crisp—just keep your eye glued to the oven so it doesn’t turn from “toasty” to “uh-oh, scorched.”
- Rest and serve. With Herculean restraint, let the bubbling beauty sit for 5 minutes before slicing. This lets everything settle and come out in neat servings (but if you scrape up the cheesy corners for a “test bite,” we’re officially friends for life).
Flavor Twists & Variations
- Add veggies: Toss in a handful of frozen peas, corn, or mixed veggies along with the beef for extra sweetness and color. Got extra mushrooms, peppers, or spinach? Sauté and stir them in for a veggie-forward twist.
- Spice it up: Smoked paprika, chili powder, or Italian herbs in the beef will totally change up the vibe. If you’re a taco lover, a spoonful of taco seasoning plus pepper jack cheese = new weeknight favorite.
- Soup swap: Not a mushroom person? Cream of chicken or celery is equally cozy. “Cream of bacon” (yep, it’s a thing!) if you’re feeling fancy, or go dairy-free with your favorite substitution.
- Cheese it up: Mix it up with Monterey Jack, Colby, Gruyere, or a fancy blend (aka “whatever’s left in the cheese drawer”).
- Make it mini: Halve the recipe and bake it in an 8×8—even just for two, it comes out perfectly. Check a little early for doneness.
