Ingredients

• 2 tablespoons olive oil
• 1 large yellow onion, diced
• 3 cloves garlic, minced
• 2 medium carrots, sliced
• 2 medium zucchini, sliced
• 2 cups broccoli florets
• 1 medium red bell pepper, chopped
• 2 cups baby spinach
• 14 ounces canned diced tomatoes
• 1 cup heavy cream
• 1 cup grated Parmesan cheese
• 1.5 cups shredded mozzarella cheese
• 2 teaspoons Italian seasoning
• 1 teaspoon salt
• 0.5 teaspoons black pepper
• 2 cups cooked brown rice or quinoa (optional)

Directions

Step 1

Preheat your oven to 375°F (190°C). Grease a 9x13-inch casserole dish with a tablespoon of olive oil or cooking spray.

Step 2

Heat 2 tablespoons of olive oil over medium heat in a large skillet. Add the diced onion and cook for 3-4 minutes, until softened.

Step 3

Add the minced garlic and cook for another 1 minute, stirring frequently until fragrant.

Step 4

Add the sliced carrots, zucchini, broccoli florets, and red bell pepper to the skillet. Cook for 5-7 minutes, stirring occasionally, until the vegetables begin to soften.

Step 5

Stir in the baby spinach and cook until wilted, about 2-3 minutes.

Step 6

Add the canned diced tomatoes along with their juices. Stir in the Italian seasoning, salt, and black pepper. Let the mixture simmer for 5 minutes.

Step 7

If using, spread the cooked brown rice or quinoa evenly across the bottom of the greased casserole dish.

Step 8

Pour the vegetable mixture evenly over the rice or quinoa layer, or directly into the dish if skipping the grain base.

Step 9

In a medium mixing bowl, whisk together the heavy cream and grated Parmesan cheese. Pour this mixture evenly over the vegetables.

Step 10

Sprinkle the shredded mozzarella cheese on top of the casserole.

Step 11

Cover the casserole dish with aluminum foil and bake in the preheated oven for 20 minutes.

Step 12

Remove the foil and bake for an additional 15-20 minutes, or until the cheese on top is melted and bubbly and starts to turn golden brown.

Step 13

Remove the casserole from the oven and let it rest for 5-10 minutes before serving.
