Rice casserole is a great choice for dinner. It’s hearty, filling and delicious. It works great for gatherings, holidays or even for dinner during the week.
To save time and add more flavor, this recipe uses one can of Campbell’s® Cream of Mushroom Soup. Campbell’s® is a brand that everyone recognizes and the condensed soup is a staple in our kitchen. It’s a convenient mix-in for a variety of recipes. Mix together the mushroom soup with fresh mushrooms, rice, spices and a creamy sauce.
Ingredients You Need
- Mushrooms – Cremini mushrooms, baby belle mushrooms or sliced button mushrooms work great in casserole.
- Onion – Fresh yellow onion adds the best flavor.
- Wild Rice – A wild rice blend tastes the best.
- Campbell’s® Cream of Mushroom Soup – The soup is packed with flavor and creamy goodness.
- Vegetable Broth – This helps thin out the sauce and add even more flavor.
- Heavy Cream – You can substitute with half and half, if needed.
- Cheese – This recipe uses a combo of shredded Mozzarella cheese and Parmesan cheese to create a rich and creamy dish.
- Fresh Spices and Herbs – Garlic, thyme, rosemary, salt and pepper. Use fresh for the best flavor.
- Olive Oil – This is needed to sauté the onions and mushrooms.
- Cook the rice in advance. You can do this up to 2 days before making the casserole. To yield 3 cups of cooked wild rice, you will need about 1 1/4 cup of uncooked rice.
- Use fresh herbs for the best flavor. You will not get the same result with dried herbs.
- Bake the casserole in a 3-quart dish. You can use a rectangular, square or oval dish for baking.
- Prep ahead: You can prep this casserole up to 1 day in advance. Prepare the casserole through step 4. After adding the cheese, cover and place in the refrigerator until you are ready to bake.
- Don’t skip the broiling. Broil the casserole for up to 5 minutes after baking to achieve that nice golden crust on the top.
- Serve the rice on its own for a full meal or as a side dish.
