Vegetarian Stuffed Peppers (with Mushrooms and Feta): How It’s Done

Step 1: Prepare the Peppers
Start by preheating your oven to 375°F (190°C). While the oven heats, carefully slice the tops and bottoms off the bell peppers. This will allow them to stand upright and be easily stuffed. Remove the seeds and membranes from the inside, ensuring they are clean and ready for filling.
Step 2: Cook the Rice
If you are using brown rice, cook it according to package instructions. If you’re opting for frozen cauliflower rice, simply heat it according to the package directions. Set aside once cooked.
Step 3: Sauté the Vegetables
In a large skillet, heat 4 teaspoons of olive oil over medium heat. Add the finely chopped onion and sauté for about 5 minutes until softened and translucent. Next, add the chopped mushrooms to the skillet, cooking until they release their moisture and become tender, about another 5-7 minutes.
Step 4: Season the Mixture
Sprinkle in the Greek seasoning and add fresh ground black pepper to taste. Stir to combine and allow the flavors to meld for an additional 2 minutes. Remove from heat.
Step 5: Combine the Filling
In a mixing bowl, combine the sautéed mushroom and onion mixture with the cooked brown rice (or cauliflower rice) and crumbled feta cheese. Mix well until all ingredients are evenly distributed.
Step 6: Stuff the Peppers
Carefully spoon the filling into each prepared bell pepper, packing it tightly but not overstuffing. Place the stuffed peppers upright in a baking dish.
Step 7: Bake
Cover the baking dish with aluminum foil and place it in the preheated oven. Bake for 30 minutes. After 30 minutes, remove the foil and bake for an additional 10-15 minutes, or until the peppers are tender and slightly charred on top.
Health-Conscious Tweaks

- For a lower-calorie option, substitute the feta cheese with a low-fat cheese or omit it altogether.
- Incorporate additional vegetables like spinach, zucchini, or kale into the filling for extra nutrients.
- Use quinoa instead of brown rice for a protein-packed alternative.
- Opt for whole grain or gluten-free rice to accommodate various dietary needs.
What Not to Do
- Don’t overcrowd the skillet when sautéing the mushrooms; this can cause them to steam rather than brown.
- Avoid overcooking the peppers; they should retain some bite for the best texture.
- Don’t skip the seasoning! The right amount of Greek seasoning elevates the entire dish.
- Do not stuff the peppers too tightly; they need space to cook evenly.
Prep Ahead & Store
You can prepare these Vegetarian Stuffed Peppers (with Mushrooms and Feta) ahead of time. Assemble the stuffed peppers and store them in the refrigerator for up to 2 days before baking. If you prefer, you can also freeze the unbaked peppers for up to 3 months. To bake from frozen, simply increase the baking time by 10-15 minutes.
Top Questions & Answers
