🥘 What Is Ground Beef Casserole?
A ground beef casserole is a baked dish where browned beef is layered or mixed with starch (like pasta, rice, or potatoes), vegetables, and a creamy or tomato-based sauce, then topped with cheese and baked until bubbly and golden.
It’s popular because it’s:
- Budget-friendly
- Great for meal prep
- Easy to customize
- Family-friendly and freezer-safe
🛒 Basic Ingredients
This version uses simple pantry staples:
Main ingredients:
- 1 lb (450 g) ground beef
- 1 small onion, diced
- 2–3 cloves garlic, minced
- 2 cups cooked pasta (penne, elbow, or rotini)
- 1 can (15 oz) tomato sauce or marinara
- 1/2 cup sour cream or cream cheese
- 1 cup shredded cheddar cheese (plus more for topping)
- 1 cup frozen or canned vegetables (peas, corn, or mixed veg)
Seasonings:
- Salt and black pepper
- 1 tsp paprika
- 1 tsp Italian seasoning
- Optional: chili flakes for heat
👩🍳 Step-by-Step Method
1. Prepare your oven and baking dish
Preheat your oven to 375°F (190°C).
Lightly grease a medium baking dish (about 9×13 inches works well) to prevent sticking and make cleanup easier.
2. Cook the ground beef
In a large skillet over medium heat:
- Add the ground beef
- Break it apart with a spatula as it cooks
- Cook until browned and no pink remains
Once browned:
- Drain excess fat (important for avoiding a greasy casserole)
- Add diced onion and garlic
- Cook for 3–4 minutes until softened and fragrant
3. Build the flavor base
Now season the beef mixture:
- Add salt, pepper, paprika, and Italian seasoning
- Stir well so the spices coat the meat evenly
Next:
- Pour in the tomato sauce
- Stir and let it simmer for 3–5 minutes
This step helps the flavors deepen and creates a rich, cohesive sauce.
