Creating Cheesy Hamburger Rice Casserole is a simple process that you can follow easily. Just stick to the steps below for a delicious result:

1. Preheat Oven: Start by preheating your oven to 350°F (175°C).
2. Cook Ground Beef: In a large skillet over medium-high heat, add a drizzle of oil. Once hot, add the ground beef. Cook until brown, breaking it up as it cooks, about 5-7 minutes. Drain excess grease.
3. Add Onions and Garlic: To the skillet, add chopped onions and minced garlic. Sauté until onions are translucent, about 3-4 minutes.
4. Mix Ingredients: Stir in the beef broth, cream of mushroom soup, rice, frozen vegetables, salt, pepper, paprika, Italian seasoning, and crushed red pepper flakes.
5. Combine: Mix everything thoroughly until well combined.
6. Transfer to Baking Dish: Pour the mixture into a greased 2.5-quart casserole dish, spreading it evenly.
7. Add Cheese: Sprinkle shredded cheddar cheese over the top of the casserole.
8. Cover with Foil: Cover the dish with aluminum foil to retain moisture.
9. Bake: Bake in the preheated oven for 30 minutes. Remove the foil and continue baking for an additional 10-15 minutes or until the rice is tender and cheese is bubbling.
10. Rest Before Serving: Once done, remove from the oven and let it sit for 5-10 minutes. This helps it set for easier serving.

With these clear steps, you’ll find that cooking Cheesy Hamburger Rice Casserole is straightforward and enjoyable!
