Ingredients & Tools
- 4 large bell peppers (any colour, but a mix looks beautiful)
- 1 cup uncooked quinoa, rinsed well
- 1 (400g) can black beans, rinsed and drained
- 1 cup frozen corn, thawed
- 1 medium onion, finely diced
- 2 cloves garlic, minced
- 1 (400g) can diced tomatoes, undrained
- 1 tsp ground cumin
- 1 tsp smoked paprika
- 1/2 tsp chilli powder (optional, for a little kick)
- 1 1/2 cups shredded cheese (a Mexican blend or cheddar works great), divided
- 2 tbsp olive oil
- Salt and black pepper to taste
- Fresh cilantro or parsley for garnish (optional)
Tools: A large baking dish (like a 9×13 inch), a medium saucepan, a large skillet, a sharp knife, and a cutting board.
Don’t skip rinsing the quinoa—it really makes a difference in removing its natural bitter coating. And using a mix of bell pepper colours isn’t just for looks; they each have a slightly different sweetness that makes every bite a little unique.

Before You Start: Tips & Ingredient Notes
- Choosing Your Peppers. Look for peppers that are roughly the same size and that can stand upright on their own. If they’re a bit wobbly, you can slice a very thin piece off the bottom to create a flat base—just be careful not to cut through the pepper!
- To Rinse or Not to Rinse Quinoa? You really, really should rinse it. Quinoa has a natural coating called saponin that can taste quite soapy or bitter. A fine-mesh strainer under cold running water for a minute or two is all it takes to fix this.
- Spice Level Control. The chilli powder is completely optional. If you’re serving to kids or prefer a milder flavour, just leave it out. The smoked paprika and cumin will still give you loads of warm, smoky flavour without any heat.
- Cheese Matters. I highly recommend grating your own cheese from a block. Pre-shredded cheese often contains anti-caking agents that can prevent it from melting as smoothly and beautifully as freshly grated cheese.
How to Make Quinoa Stuffed Peppers
Step 1: Prep the Peppers & Quinoa. First, preheat your oven to 190°C (375°F). Carefully slice the tops off your bell peppers and remove the seeds and white membranes from inside. Give them a good rinse. Now, cook your quinoa according to the package instructions—usually, it’s 1 cup quinoa to 2 cups water, brought to a boil then simmered for about 15 minutes until the water is absorbed. Fluff it with a fork and set it aside.
Step 2: Sauté the Aromatics. While the quinoa is cooking, heat the olive oil in a large skillet over medium heat. Add the diced onion and cook for about 5-7 minutes, until it becomes soft and translucent. You’ll notice a lovely sweet aroma. Then, add the minced garlic and cook for just one more minute—you don’t want the garlic to burn!
Step 3: Build the Filling. To the skillet with the onions and garlic, add the can of diced tomatoes (with their juices), the rinsed black beans, thawed corn, cumin, smoked paprika, and chilli powder if using. Stir everything together and let it simmer for about 5 minutes, allowing the flavours to meld. Season generously with salt and black pepper.
Step 4: Combine Everything. Now, take your cooked, fluffy quinoa and add it to the skillet. Stir it all together until it’s perfectly combined. Turn off the heat and stir in one cup of the shredded cheese. The heat from the mixture will start to melt the cheese, creating a wonderfully gooey binding agent for the filling.
Step 5: Stuff ‘Em Up! Place your hollowed-out peppers in a baking dish. If they’re still a bit wobbly, remember the trick of shaving a tiny bit off the bottom. Spoon the quinoa filling into each pepper, pressing down gently as you go to pack it in. You want them heaping full! Top each pepper with the remaining half cup of cheese.
Step 6: Bake to Perfection. Pour about a half-inch of water into the bottom of the baking dish around the peppers. This creates a bit of steam in the oven, which helps to cook the pepper shells until they’re beautifully tender. Bake for 30-35 minutes, until the peppers are soft (you can test this by piercing one with a knife) and the cheese on top is golden and bubbly.
Step 7: Rest and Serve. Carefully remove the baking dish from the oven. Let the peppers sit for about 5 minutes before serving—they will be incredibly hot! This resting time allows the filling to set just a little bit. Garnish with fresh cilantro or parsley if you like, and dig in.

Complementary Dishes
- A Simple Green Salad with a Lime Vinaigrette — The crisp, acidic salad cuts through the richness of the cheese and provides a refreshing contrast to the warm, baked peppers.
- Cooling Avocado Slices or Guacamole — The creamy, cool texture of avocado is the perfect partner for the spiced quinoa filling. It adds a lovely richness without being heavy.
- A Dollop of Greek Yoghurt or Sour Cream — Just a spoonful on the side adds a tangy creaminess that balances the smoky spices beautifully, especially if you added the chilli powder.
Drinks
- A Crisp Mexican Lager — The light, bubbly beer is fantastic for cleansing the palate between bites and its mild bitterness complements the spices.
- Sparkling Water with Lime — For a non-alcoholic option, the bubbles and citrus zing are incredibly refreshing and highlight the fresh flavours in the peppers.
- A Zesty Paloma — The grapefruit and tequila in this cocktail have a brightness that stands up to the hearty, savoury filling wonderfully.
Something Sweet
- Mango Sorbet — The tropical fruitiness feels like a natural progression from the meal and its icy coldness is a delightful finish.
- Dark Chocolate-Dipped Orange Slices — A simple, elegant dessert where the dark chocolate echoes the smoky notes of the paprika and the orange provides a fresh, sweet burst.
- Churros with Chocolate Sauce — If you really want to lean into the theme, these warm, cinnamony treats are a fun and indulgent way to end the night.
Top Mistakes to Avoid
- Mistake: Not parboiling or using raw, hard peppers. If you just stuff a raw pepper and bake it, the filling will be done long before the pepper is tender. The steam from the water in the baking dish is crucial for getting that perfect, soft-but-not-mushy pepper texture.
- Mistake: Underseasoning the filling. The quinoa and beans act like little flavour sponges, so you need to be a bit generous with the salt and spices. Taste the filling before you stuff the peppers—it should taste delicious on its own!
- Mistake: Overstuffing without packing. You want to heap the filling in, but you also need to press it down gently with the back of your spoon as you go. This ensures you get a solid, cohesive stuffed pepper that doesn’t fall apart when you cut into it.
- Mistake: Skipping the water in the baking dish. I’ve messed this up before too, thinking it wasn’t important. Trust me, it is! Without that steam, the pepper skins can become tough and leathery instead of tender.
Expert Tips
- Tip: Add a flavour boost to your quinoa. Instead of cooking your quinoa in plain water, try using vegetable broth. It infuses the quinoa with a savoury depth from the inside out, making the entire dish more flavourful.
- Tip: For a crispier top, use the broiler. If you love a bit of extra browning and crunch on your cheese, pop the baking dish under the broiler for the last 1-2 minutes of cooking. Watch it like a hawk though—it can go from golden to burnt in seconds!
- Tip: Make them ahead for easy entertaining. You can assemble the peppers completely, cover the dish, and refrigerate them up to 24 hours in advance. Just add a few extra minutes to the baking time since you’re starting from cold.
- Tip: Freeze your leftovers beautifully. These peppers freeze exceptionally well. Cool them completely, wrap each pepper individually in foil, and place them in a freezer bag. To reheat, bake from frozen in a 180°C (350°F) oven until heated through.
FAQs
Can I use a different grain instead of quinoa?
Absolutely! Cooked brown rice, farro, or even couscous would work well as a substitute. The cooking method for the grain will be different, so just make sure you have about 3 cups of cooked grain to replace the quinoa. The key is to use a grain that won’t get too mushy when baked. Brown rice is probably the closest in texture and heartiness.
How do I know when the peppers are fully cooked?
The best test is the knife test. Take a sharp paring knife and carefully pierce the side of a pepper. If it slides in with very little resistance, similar to a baked potato, it’s done. The pepper skin will also look slightly wrinkled and softened, and the cheese on top will be beautifully melted and bubbly.
Can I make this recipe vegan?
Easily! Just omit the cheese or use your favourite vegan shredded cheese. To add back some creaminess and richness, you could stir a couple of tablespoons of nutritional yeast into the filling for a cheesy flavour, or add some diced avocado after baking.
My filling is a bit dry. What happened?
This usually means the quinoa absorbed a bit too much liquid. Next time, make sure to include the juices from the canned tomatoes, as that’s a key source of moisture. If it happens, you can stir a tablespoon or two of tomato sauce, salsa, or even a little water into the filling mixture before stuffing the peppers.
Are these peppers spicy?
As written, with the optional chilli powder omitted, they are not spicy at all—just warmly spiced from the cumin and smoked paprika. The heat level is completely in your control. If you want spice, add the chilli powder, some diced jalapeño to the filling, or even a dash of hot sauce when serving.
