Bell peppers are roasted until tender, then filled with herbed quinoa, sautéed zucchini and cherry tomatoes, and finished with a drizzle of blended cashew cream. The whole thing comes together in about an hour with one skillet and one baking dish. It’s a complete meal that holds up well the next day, which makes it worth the effort.
Why this recipe works
Two things actually matter here. First, the peppers go into the oven cut-side down for the initial roast. This traps steam inside the pepper walls and softens them evenly without drying out the edges — cut-side up and you risk leathery tops before the base is tender. Second, the cashew cream is blended until completely smooth and kept thin enough to pour. It isn’t a thick sauce you spoon on; it seeps into the filling and pulls the quinoa, vegetables, and pepper together into something cohesive rather than three separate components sitting in a bowl.
What can go wrong
- Watery filling: Zucchini releases a lot of liquid as it cooks. If you don’t sauté it long enough to drive off that moisture before mixing it into the quinoa, the filling turns soggy inside the pepper. Cook the zucchini until it looks slightly dry at the edges, not just softened.
- Peppers that tip over in the pan: Tall, narrow peppers won’t sit flat once halved and filled. Choose peppers with a wide, flat base, or trim a very thin slice off the bottom of each half before filling — just enough to create a flat surface without cutting through.
- Gritty cashew cream: If the cashews weren’t soaked long enough or your blender isn’t high-powered, the cream will have a grainy texture. Soak for at least four hours, or use boiling water for a 30-minute quick soak. Blend for a full two minutes and taste before you stop.
- Underseasoned filling: Quinoa absorbs salt slowly. Season the filling after it’s fully mixed and has had a minute to sit, not just right after you add the salt. Taste again before stuffing the peppers — what seems adequate in the skillet will taste flat once it’s inside the pepper.
- Cashew cream that seizes up: If the cream sits in the fridge and thickens to a paste, whisk in water a teaspoon at a time until it’s pourable again. Don’t reheat it in a pan — it can break and turn grainy.
Vegan Stuffed Peppers with Herbed Quinoa and Cashew Cream
Equipment
- Large skillet
- Medium saucepan
- High-speed blender or food processor
- Baking dish
- Oven
Ingredients
Stuffed Peppers
- 4 large bell peppers (any color) Tops cut off, deseeded and hollowed
- 1 tablespoon olive oil extra virgin preferred
- 1 cup yellow onion, diced about 1 medium onion
- 3 cloves garlic, minced
- 1 cup zucchini, finely chopped organic if possible
- 1 cup cherry tomatoes, halved preferably heirloom
- 1 teaspoon sea salt or to taste
- ½ teaspoon black pepper freshly ground
- 1 ½ cups cooked quinoa cooled slightly
- ½ cup fresh parsley, chopped flat-leaf preferred
- ½ teaspoon oregano, dried
Cashew Cream Topping
- 1 cup raw cashews soaked in hot water for 1 hour or overnight for creaminess
- ½ cup water
- 1 tablespoon lemon juice freshly squeezed
- ½ teaspoon sea salt
Instructions
- Preheat your oven to 375°F (190°C). Lightly grease the base of a baking dish with olive oil.
- In a large skillet over medium heat, add 1 tablespoon of olive oil. Add diced onion and sauté for 5–7 minutes, or until translucent and fragrant.
- Add minced garlic, chopped zucchini, and heirloom cherry tomatoes. Cook for 7–10 minutes until the vegetables soften and slightly caramelize. Season with sea salt and black pepper.
- Remove the skillet from heat and stir in the cooked quinoa, fresh parsley, and dried oregano. Toss gently to combine and taste for seasoning.
- Stuff each bell pepper generously with the quinoa-vegetable mixture. Arrange them upright in the prepared baking dish.
- Cover the dish with aluminum foil and bake for 30 minutes. Then uncover and bake an additional 10 minutes to slightly brown the tops.
- While the peppers bake, prepare the cashew cream. Drain soaked cashews and add them to a high-speed blender along with water, lemon juice, and salt. Blend on high for 1–2 minutes or until smooth and creamy.
- Once peppers are done, allow to cool for 5 minutes. Drizzle with cashew cream, garnish with extra parsley, and serve warm.
Notes
- For faster prep, cook the quinoa a day ahead and store it in the fridge.
- To enhance umami, add 1 tablespoon of nutritional yeast to the filling mix.
- The stuffed mixture can also be used in roasted zucchini halves or mushrooms for variety.

Common questions
Can I make the filling ahead of time?
Yes — the quinoa filling keeps well in the fridge for up to three days. Store it separately from the peppers and stuff them just before baking so the peppers don’t steam and soften prematurely in the fridge.
What if I don’t have a high-speed blender for the cashew cream?
A standard blender works if you soak the cashews for the full four hours and blend longer than you think necessary — closer to three minutes. Stop and scrape the sides down once or twice during blending.
Can I use a different grain instead of quinoa?
Cooked millet or bulgur wheat both work well here. Avoid brown rice — it’s too dense and doesn’t absorb the herb flavors as readily, so the filling ends up starchy rather than savory.
How do I store and reheat leftovers?
Store stuffed peppers in an airtight container in the fridge for up to three days. Reheat them covered in a 350°F oven for about 15 minutes — skip the microwave if you can, since it makes the pepper walls rubbery. Add a fresh drizzle of cashew cream after reheating, not before.
Can I freeze these?
Freeze the filling on its own, not the assembled peppers. Roasted pepper walls turn mushy after freezing and thawing. Defrost the filling in the fridge overnight, then roast fresh peppers and stuff them when you’re ready to eat.
My peppers are done but the filling looks dry — what happened?
The quinoa likely absorbed too much liquid during the sauté step, or the peppers were in the oven uncovered the whole time. Cover the baking dish with foil for the first 20 minutes of the filled bake, then uncover for the last 10. A spoonful of vegetable broth stirred into the filling before stuffing also helps.
