Ingredients
The casserole uses ground beef, tomatoes, Rotel, egg noodles, sour cream and a three-cheese topping. Here are the amounts used in the recipe card:
- 1 pound ground beef (or try turkey, spicy sausage, or a mix—no one’s judging)
- 1 (14.5 oz) can diced tomatoes (juice and all)
- 1 (10 oz) can Rotel tomatoes & green chilies (for a gentle, happy kick—sub mild if you’re spice-sensitive)
- 1 (6 oz) can tomato paste
- 1 teaspoon salt
- 1/4 teaspoon black pepper
- 1/4 teaspoon each: onion powder, garlic powder
- 6 oz medium egg noodles
- 1 cup sour cream (Greek yogurt stands in beautifully, especially if you forgot the sour cream like I do every third time)
- 1 cup shredded cheddar cheese
- 1 cup grated Parmesan cheese
- 1 cup shredded mozzarella cheese
Cook the egg noodles only until al dente so they stay firm during baking.
Directions
Ready for dinner magic? Here’s your play-by-play (plus a few tips I’ve learned along the way):
- Preheat the oven to 350°F. Lightly spray a 9×13-inch casserole dish so you’re not chiseling baked cheese off later. Trust me.
- Bring a pot of salted water to a boil. Cook the 6 ounces of egg noodles according to the package directions until al dente, drain well, then toss with the sour cream.
- Brown the ground beef in a large skillet, breaking it into crumbles. Verify it reaches 160°F (71°C) with a food thermometer, then drain excess fat.
- Stir in the diced tomatoes with juice, Rotel, tomato paste, salt, pepper, onion powder and garlic powder. Simmer over low heat for 20 minutes, stirring occasionally.
- Layer the sour cream noodles in your dish first, then spoon all of that meaty tomato sauce over the top. If it looks rustic and messy, you’re doing it right.
- In a bowl, mix together the cheddar, Parmesan, and mozzarella—then shower the whole casserole with this glorious cheesy blend. Sometimes I throw in a full extra handful because… cheese.
- Cover with foil and bake for 35 minutes. Uncover and bake for 5–10 minutes more, until the casserole is hot and bubbly and the cheese is melted.
- Let it sit for about 5 minutes before cutting. The cheese settles, flavors mingle, and your patience gets rewarded.

Serve it hot, with a side of garlic bread or a crisp green salad if you’re feeling virtuous. (Sometimes dinner is just this casserole and a fork—no judgment.)
Variations
I’m a big fan of using up what’s on hand or switching things up to keep dinner interesting. Try these easy twists: For another easy option, see our Hobo Casserole Rustic Ground Beef and Potato Bake.
- Switch the protein: Ground turkey or chicken for lighter vibes, or go bold with Italian sausage.
- Add some veggies: Sautéed mushrooms, spinach, peppers, or even a few handfuls of chopped zucchini work great. Extra nutrition and you still get all that comfort.
- Make it spicy: Add a few shakes of hot sauce, a pinch of crushed red pepper, or sliced jalapeños if your family likes heat.
- Use gluten-free pasta: No reason why anyone should be left out of this cheesy deliciousness.
- Want to sneak in more protein? Use Greek yogurt instead of sour cream, or toss in a handful of white beans with the sauce.
The fun of casseroles is making them your own. Some of my favorite versions started because I needed to clear out the fridge!
Storage and Reheating
Refrigerate leftovers in a covered container within 2 hours and use them within 3–4 days. Reheat portions to 165°F (74°C). For make-ahead preparation, assemble the casserole, cover and refrigerate for up to one day; add a few minutes to the baking time and verify the center is hot.

Instructions
- Preheat your oven to 350°F (175°C). Lightly spray a 9×13-inch baking dish with cooking spray and set it aside.

- Spread the sour cream-coated noodles evenly across the bottom of the prepared baking dish. Spoon the meat sauce over the noodles, spreading it out with a spatula to ensure it’s evenly distributed.
