Ingredient insights & tweaks

• Cooked grains: Chewy and slightly sticky. Overcooked? Add a splash of broth to loosen the mixture.
• Herbs & spices: Fresh herbs add brightness, dried herbs deepen flavor. Adjust to taste and season generously.

• Nuts or seeds: Add crunch and richness. Chopped walnuts or sunflower seeds work well for texture.

Spotlight on bell peppers and grains

Bell peppers:

• Their sweet, smoky aroma intensifies as they roast. Look for shiny, unblemished skins.
• A slight give when pressed indicates perfect doneness—firm but not hard.

Cooked grains:

• Their chewy texture absorbs flavors beautifully. Slightly toasty when stir-fried, adding depth.
• They should be fluffy and moist, not sticky or dry—overcooking makes them mushy.

Ingredient substitutions for your pantry and preferences

• Dairy-Free: Swap vegan cheese or nutritional yeast for cheesy flavor without dairy.
• Gluten-Free: Use certified gluten-free grains like millet or quinoa for a celiac-safe dish.
• Spice Variations: Add cayenne or smoked paprika for heat and smoky depth.
• Herb Choices: Swap parsley for cilantro or basil for different freshness.
• Grain Swap: Use lentils or chopped mushrooms instead of grains for a different texture.

Equipment & Tools

• Baking dish: Holds the peppers upright during baking
• Skillet: Sautéing the aromatics and grains
• Knife: Cutting peppers and chopping ingredients
• Spoon or spatula: Stuffing peppers and mixing filling

Step-by-step: How to make vegan stuffed peppers

1. Preheat oven to 200°C (392°F).
2. Cut the tops off peppers and remove seeds. Place upright in a baking dish.
3. Heat a tablespoon of oil in a skillet over medium heat. Sauté chopped onion and garlic until translucent, about 5 minutes.
4. Add the cooked grains, chopped herbs, and a squeeze of lemon juice. Season with salt and pepper. Stir well.
5. Stuff each pepper with the grain mixture, pressing down slightly.
6. Sprinkle a little nutritional yeast or vegan cheese on top for extra flavor.
7. Bake for 20-25 minutes, until peppers are tender and filling is slightly browned on top.
8. Remove from oven and let rest for 5 minutes before serving.

Let the peppers rest for 5 minutes to settle flavors. Serve warm, garnished with fresh herbs or a drizzle of olive oil.

How to Know It’s Done

• Peppers should be bright and firm before baking.
• Filling should be heated through and slightly browned on top.
• Peppers should be tender but not mushy after baking.

Tips & tricks for perfect stuffed peppers

• Keep the filling moist but not soggy—use just enough lemon juice or broth.
• Roast peppers cut-side down first for better caramelization.
• Use a filling mixture that’s slightly looser than you think—it expands during baking.
• Sprinkle nutritional yeast on top before baking for extra umami.
• For a smoky flavor, toss peppers with smoked paprika before roasting.

Common mistakes and how to fix them

• FORGOT TO preheat the oven? Turn it on now, and cover peppers with foil to prevent drying.
• DUMPED too much water into filling? Drain excess or add a bit more grain to balance moisture.
• OVER-TORCHED the top? Cover with foil and bake a little longer, or broil briefly for a crispy top—watch closely.
• FELL apart when serving? Let the peppers rest for 5 minutes — they’ll hold together better.

Quick fixes when things go awry

• When peppers are too firm, cover with foil and bake 5 more minutes.
• Splash a little vinegar or lemon juice if filling tastes flat.
• Patch over cracked peppers with extra filling and bake longer.
• Shield peppers with foil if tops brown too quickly.
• When in doubt, reheat in a covered skillet with a splash of water to steam gently.

Make-ahead and storage tips

• Prepare the filling a day ahead; store in an airtight container in the fridge for up to 2 days.
• Stuffed peppers can be assembled a few hours before baking; keep refrigerated.
• Leftovers keep in the fridge for 3 days; reheat in the oven at 180°C (356°F) for 10 minutes.
• The flavor deepens overnight, making it even more satisfying the next day.
