Ingredients
Below, I discuss the ingredients and possible substitutions if you don't have a specific ingredient. However, if you are looking for the specific measurements of each ingredient, scroll down to the bottom of this article, just above the comments, for the printable recipe card, which includes all the ingredients and the specific amounts of each one.
- Ground beef: This gives the casserole a savory and meaty flavor. You can use ground turkey or ground chicken instead to change it up.
- Olive oil: This adds moisture and a subtle, fruity flavor to the casserole. You can also use avocado oil, vegetable oil, or canola oil instead.
- Red bell peppers: These add color and a sweet, slightly smoky flavor to the casserole. You can use a yellow or orange bell pepper instead of a red bell pepper for the same sweet flavor.
- Green bell peppers: They give the casserole a mild, fresh taste and add pops of green color to the dish.
- Medium onion: Onions give a strong, aromatic base flavor to the casserole. I used a red onion, but you can use white or yellow onions.
- Garlic: Adds flavor to the casserole. You can use garlic powder or granulated garlic as a substitute.
- Italian seasoning: This is a seasoning blend that contains herbs like basil, oregano, rosemary, and thyme. You can make your Italian seasoning blend or use your favorite seasoning blend.
- Salt and black pepper: Add these to taste.
- Smoked paprika: It adds a smoky, earthy note to the casserole. Regular paprika can be used instead if you don’t have smoked paprika.
- Long-grain white rice: I used rinsed Basmati rice for this recipe. You can use cauliflower or brown rice, but adjust the cooking time and liquid accordingly.
- Diced tomatoes with juices: They add moisture and tomato flavor to the recipe. I use fire-roasted tomatoes, but you can use fresh diced tomatoes, canned tomato sauce, and tomato paste as a replacement.
- Beef broth: Broth is added to help cook the rice and infuse the casserole with a savory beefy flavor. You can use chicken broth, vegetable broth for a vegetarian version, or water with bouillon cubes.
- Shredded cheddar cheese: This gives the casserole a creamy, cheesy topping. You can use your favorite cheese blends, such as mozzarella cheese, pepper jack cheese, Monterey Jack, or a dairy-free cheese alternative.
