  • 2.5 cups freshly grated Parmesan cheese, divided

Instructions
 

Preparation

  • Measure 3 cups of dry instant brown rice and cook it according to the package directions. Once fluffy and tender, set aside.
  • In a large skillet or Dutch oven, heat olive oil over medium-high heat. Add diced onions, minced garlic, carrots, salt, and pepper. Cook for 10-15 minutes until the onions are translucent and the carrots are tender, stirring occasionally.
  • Add frozen peas, frozen broccoli, both cans of cream of mushroom soup, 1½ cups of Parmesan, and 1 cup of cheddar cheese. Stir until heated through (about 10-12 minutes).
  • Combine the cooked rice and chopped parsley with the vegetable mixture. Stir well to blend the flavors together.
  • Grease a 9x13-inch casserole dish and spread the mixture evenly.
  • Sprinkle the remaining Parmesan and cheddar cheese on top.

Baking

  • Preheat your oven to 400°F and bake for 10-15 minutes until the cheese is bubbly and golden brown.
  • Let cool before serving.

Notes

For added flavor, consider sautéing the garlic and onions until fragrant. Substitute the cheeses based on your preferences. You can also use pre-cut fresh vegetables to streamline preparation.
