Ingredients

(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)

4 large yellow bell peppers
1 cup uncooked brown rice
8 ounces Baby Bella (cremini) mushrooms, sliced
1 cup fresh cilantro, finely chopped
1 cup mozzarella cheese, shredded
10 ounces cream of mushroom soup
10 ounces cream of celery soup
2 teaspoons minced garlic
1 teaspoon black pepper
1 teaspoon dried oregano
1/2 teaspoon ground thyme
1/2 teaspoon garlic powder
1/2 teaspoon sea salt
1 tablespoon olive oil

Directions

Begin by cooking the brown rice according to the package instructions. Once cooked, set it aside and allow it to cool slightly.

Preheat your oven to 375°F (190°C).

Prepare the bell peppers by cutting off the tops or slicing them in half lengthwise. Remove the seeds and membranes from inside each pepper and set them aside.

Heat olive oil in a skillet over medium heat. Add the sliced mushrooms and sauté them for about 5 to 10 minutes until they soften and release their moisture.

In a large mixing bowl, combine the cooked brown rice, sautéed mushrooms, chopped cilantro, cream of mushroom soup, cream of celery soup, minced garlic, black pepper, oregano, ground thyme, garlic powder, and sea salt. Mix everything together until the ingredients are evenly incorporated.

Fill each bell pepper half generously with the rice and mushroom mixture. Sprinkle shredded mozzarella cheese evenly over the top of each stuffed pepper.

Place the stuffed peppers on a baking sheet or baking dish. Bake them in the preheated oven for about 35 minutes, until the peppers are tender and the cheese is melted and lightly golden.

Remove from the oven and allow the peppers to cool for a few minutes before serving.

Variations

You can easily customize this recipe depending on your preferences or ingredients available in your kitchen.

Add vegetables such as diced zucchini, spinach, or corn to the filling for extra nutrients and color.

Swap brown rice with quinoa, white rice, or cauliflower rice if you want a different texture or a lower-carb option.

Use different cheeses such as Monterey Jack, cheddar, or a blend of Italian cheeses for a richer flavor.

If you prefer a slightly spicy version, add crushed red pepper flakes or diced jalapeños to the filling mixture.

For extra protein, mix in cooked lentils or chickpeas.

Storage/Reheating

Store leftover stuffed bell peppers in an airtight container in the refrigerator for up to 4 days.

To reheat in the microwave, place a stuffed pepper on a microwave-safe plate and heat for 1 to 2 minutes until warmed through.

For oven reheating, place the peppers in a baking dish, cover loosely with foil, and warm at 350°F (175°C) for about 15 minutes.

If you want to freeze them, wrap each stuffed pepper individually and store them in a freezer-safe container for up to 2 months. Thaw overnight in the refrigerator before reheating.
