Step-by-Step Cooking Instructions

Let’s get started with making your Simple Ground Beef Casserole! Follow these easy steps:
Step 1: Cook the Pasta or Rice
If you’re using pasta, cook it according to the package instructions until al dente. Drain and set aside. If you prefer rice, cook 1 ½ cups of white or brown rice and set it aside.
Step 2: Sauté the Ground Beef
In a large skillet, heat 1 tablespoon of olive oil over medium heat. Add the diced onions and garlic and sauté for 2-3 minutes until softened. Add the ground beef, season with salt and pepper, and cook until browned, about 7-8 minutes. Break the beef into small pieces as it cooks. Drain any excess fat.
Step 3: Add the Sauce
Once the beef is fully cooked and drained, stir in the tomato sauce and Italian seasoning (or any herbs you’re using). Let the mixture simmer for 5 minutes to allow the flavors to meld together.
Step 4: Combine Ingredients
Preheat your oven to 375°F (190°C). In a large mixing bowl, combine the cooked pasta or rice with the ground beef mixture. If you’re adding sour cream for creaminess, mix it in now. Stir everything together until well combined.
Step 5: Assemble the Casserole
Grease a 9x13-inch baking dish with a little olive oil or butter. Pour the beef and pasta (or rice) mixture into the baking dish, spreading it out evenly. Top the casserole with the shredded cheese, making sure it covers the entire dish.
Step 6: Bake
Place the casserole in the preheated oven and bake for 20-25 minutes, or until the cheese is melted and bubbly. If you prefer a crispy top, broil the casserole for the last 3-5 minutes, watching closely so it doesn’t burn.
How to Cook Simple Ground Beef Casserole: A Step-by-Step Guide
- Cook your pasta or rice until al dente and set aside.
- Brown the ground beef with onions and garlic until cooked through.
- Simmer with tomato sauce and season with salt, pepper, and herbs.
- Mix everything together with pasta or rice, and transfer to a greased baking dish.
- Top with shredded cheese and bake at 375°F for 20-25 minutes until golden and bubbly.
Common Mistakes to Avoid
- Overcooking the Pasta – Make sure to cook the pasta just until al dente, as it will continue to cook slightly in the oven.
- Not Draining Excess Fat – If you don’t drain the excess fat from the ground beef, the casserole may turn out greasy.
- Under-seasoning – Be sure to season the ground beef well, as pasta or rice can be bland without enough salt and spices.
- Not Preheating the Oven – Preheat the oven before assembling the casserole to ensure even cooking.
