For the sauce:
• 1 can (14 oz) diced tomatoes or 1 can (10 oz) tomato soup
Or alternatively:• 1 cup sour cream and 1/2 cup cream of mushroom soup for a creamy version
Cheese:
• 1 ½ to 2 cups shredded cheese (cheddar, mozzarella, or a blend)
Step-by-Step Method:
1. Preheat the oven
Start by preheating your oven to 375°F (190°C). This ensures your casserole bakes evenly once assembled.
2. Cook the pasta or potatoes
If using pasta, boil it in salted water until just al dente (firm to the bite), then drain and set aside.
If using potatoes, boil them in lightly salted water for about 10–12 minutes until just tender, then drain.
3. Prepare the ground beef mixture
• In a large skillet over medium heat, cook the ground beef until browned and fully cooked.
• Add the chopped onions, bell peppers, and mushrooms. Cook for about 5–7 minutes until the vegetables soften.
• Stir in the minced garlic and cook for another minute.
• Season the mixture with salt, pepper, and Italian seasoning or paprika.
4. Add the sauce
• For a tomato-based casserole, stir in the diced tomatoes or tomato soup. Simmer for 5–10 minutes to allow the flavors to blend.
• For a creamy casserole, reduce heat to low and stir in the sour cream and cream of mushroom soup. Mix well until everything is combined and warmed through.
5. Combine everything
• In a large mixing bowl or directly in your casserole dish, mix the cooked pasta or potatoes with the beef mixture and about half of the shredded cheese.
• Stir everything together to ensure the sauce coats all the ingredients evenly.
6. Assemble the casserole
• Pour the combined mixture into a greased 9x13-inch baking dish.
• Sprinkle the remaining cheese evenly over the top.
7. Bake
• Bake uncovered in the preheated oven for 20–25 minutes, or until the casserole is bubbly and the cheese is melted and slightly golden brown.
8. Let it rest
Once out of the oven, let the casserole rest for 5–10 minutes. This helps it set and makes it easier to serve.
Serving Suggestions:
Serve your ground beef casserole hot, with a crisp green salad or steamed vegetables on the side. A slice of warm garlic bread or dinner rolls makes a perfect complement.
Make-Ahead and Storage Tips:
• Make-Ahead: Assemble the casserole ahead of time and refrigerate for up to 24 hours before baking. Add an extra 5–10 minutes to the baking time if cooking from cold.
• Freezing: Wrap tightly and freeze for up to 3 months. Thaw overnight in the fridge before baking.
• Leftovers: Store in the refrigerator in an airtight container for up to 4 days. Reheat in the oven or microwave.
Final Thoughts:
Ground beef casserole is more than just a quick fix—it’s a comforting, flexible meal that can be adapted to your tastes and pantry staples. Whether you go with a zesty tomato base or a rich, creamy sauce, this dish promises a cozy end to any busy day.
