Quinoa and Black Bean Stuffed Peppers (Gluten-Free)

Stuffed peppers are a practical meal prep recipe — the filling comes together in one skillet, the peppers roast in the oven while you clean up, and they reheat well throughout the week. This version uses quinoa and black beans for a filling that’s hearty enough to work as a standalone vegetarian main. The spice blend is simple: cumin, smoked paprika, and optional chili powder give the filling a warm, slightly smoky flavor without being overpowering.

Any color of bell pepper works here. Red, orange, and yellow are sweeter and softer after roasting; green peppers hold their shape better and have a slightly more bitter flavor.

Ingredients

• 4 large bell peppers, tops cut off and seeds removed
• 1 cup cooked quinoa (rinsed before cooking to remove bitterness)
• 1 can (400g) black beans, drained and rinsed
• 1 small onion, finely chopped
• 2 garlic cloves, minced
• 1 cup corn kernels (fresh, frozen, or canned)
• 1 cup diced tomatoes, with juice (fresh or canned)
• 1 teaspoon ground cumin
• 1 teaspoon smoked paprika
• ½ teaspoon chili powder (optional)
• Salt and black pepper to taste
• 2 tablespoons olive oil
• 1 cup shredded cheese (optional — use dairy-free for a vegan version)
• Fresh cilantro or parsley, chopped, to serve

Instructions

Step 1 — Preheat Preheat oven to 375°F (190°C). Lightly grease a baking dish with olive oil.

Step 2 — Par-roast the peppers (optional but recommended) Place the hollowed peppers cut-side up in the baking dish and roast for 10–15 minutes before filling. This gives you a more tender pepper in the final dish without needing to extend the bake time after stuffing.

Step 3 — Make the filling Heat olive oil in a skillet over medium heat. Add onion and garlic and cook for 4–5 minutes until softened. Add cumin, smoked paprika, and chili powder and stir for about a minute to let the spices bloom. Add black beans, corn, diced tomatoes with their juice, salt, and pepper. Cook for 5 minutes, stirring occasionally, until everything is heated through and the tomatoes have softened. Remove from heat and fold in the cooked quinoa.

Step 4 — Stuff the peppers Spoon the filling generously into each pepper, packing it in firmly. Arrange upright in the baking dish. If the peppers won’t stand on their own, trim a small sliver from the bottom to create a flat base.

Step 5 — Add cheese and bake Top with shredded cheese if using and cover loosely with foil. Bake for 25–30 minutes until the peppers are tender. Remove foil and bake for another 5 minutes to brown the cheese.

Step 6 — Serve Scatter fresh cilantro or parsley over the top before serving.

Tips

• Rinse quinoa thoroughly before cooking — the natural coating (saponin) tastes bitter and soapy if left on
• Use diced tomatoes with their juice rather than drained — it keeps the filling moist during baking
• If the filling looks dry before stuffing, add a splash of vegetable broth to loosen it
• Nutritional yeast stirred into the filling or sprinkled on top adds a cheesy, savory note for a dairy-free option

Variations

• Southwest: Add black olives and a squeeze of lime, top with avocado after baking
• Mediterranean: Add sun-dried tomatoes, olives, and top with crumbled feta
• Italian: Mix in basil, oregano, and diced zucchini, top with mozzarella and a spoonful of marinara
• Low-carb: Replace quinoa with cauliflower rice or riced broccoli
• Extra protein: Add cooked lentils or chickpeas alongside the black beans

Storage

• Refrigerator: up to 4 days in an airtight container
• Freezer: assemble and freeze before baking, then bake directly from frozen at 375°F adding 10–15 minutes to the bake time
• Reheat in the oven at 350°F covered with foil, or in the microwave

Frequently Asked Questions

Can I freeze these before baking? Yes. Assemble the stuffed peppers, place in a freezer-safe dish, and freeze before baking. When ready to cook, bake directly from frozen at 375°F and add 10–15 minutes to the cooking time.

What can I substitute for quinoa? Cooked brown rice, white rice, or any other gluten-free grain works well. Adjust the amount based on how much filling you want — the ratio doesn’t need to be exact.

How do I make this vegan? Skip the cheese or use a dairy-free alternative. Everything else in the recipe is already plant-based.

Why are my peppers still firm after baking? Par-roasting the peppers before filling is the most reliable way to ensure they’re fully tender. If you skipped that step and the peppers are still firm, cover with foil and return to the oven for another 10–15 minutes.

Can I make the filling ahead of time? Yes. The filling keeps well in the refrigerator for up to 3 days. Stuff and bake the peppers when you’re ready to serve.
