• Creamy Spinach Casserole

Mushrooms are the star of this easy rice casserole. They add a delicious heartiness to the meal without adding any meat! Although, you could certainly add chicken to it. That would be a wonderful way to make this a full meal.

Fresh spinach is great in casseroles as well. It is so versatile and a vegetable that truly tastes good. Looking for more spinach recipes? Why not try Greek Chicken Meatballs, or this Garlic Butter Sauteed Spinach, or maybe this Homemade Spinach Pasta.

How do you make Creamy Spinach Casserole?

Begin by preparing rice. For rice, you use a 2 to 1 ratio, 2 parts liquid to 1 part rice. In a medium sized saucepan, place rice and stock and bring to a boil, cover and turn heat to the lowest setting. The rice will take about 12 minutes from the time you place the lid on it.

While the rice is cooking, begin your sauce. Add olive oil and butter to a large saucepan on medium-high heat. Once the butter has melted, add in diced onions and allow to cook for 2-3 minutes until translucent.

Next, add your mushrooms and garlic and cook for another 5-7 minutes, until the mushrooms have started to cook down.

Turn heat down to medium low, and add milk, cream cheese, salt, and shredded parmesan. Stir until cream cheese has completely melted and everything is well combined.

Take off heat, stir in chopped spinach and cooked rice. Serve as is, or top with ½ cup of parmesan cheese and bake at 400 degrees for 20 minutes.

Recipe Tips

• Baking this in the oven is optional. Everything is already cooked through before if goes in the oven. If you don't bake it, it will remain more creamy and saucy. I love it that way! However, baking the casserole gives it a nice bubbly crust.

What can you serve this spinach bake with?

• Chicken, such as air fryer chicken thighs or crusted chicken romano.
• Air Fryer Salmon
• Tender Bavette Steak
