## About This Recipe

These Mexican Chicken & Quinoa Stuffed Peppers are built to be weeknight-friendly without feeling like a compromise: shredded chicken and a modest amount of cooked quinoa create a flexible, high-protein filling while salsa and sautéed onion keep everything juicy and bright. The recipe yields six medium bell peppers (serves 6) — 2/3 cup dry quinoa cooks to roughly 2 cups — and when combined with 2 cups shredded chicken, 1 cup black beans, 1 cup corn, 1/2 cup salsa and cheese you get about 7½–8 cups of filling, which equates to approximately 1–1¼ cups of filling per pepper. A 9x13-inch baking dish will hold six upright peppers comfortably.

What makes this version work is balance: quinoa gives a slightly nutty chew that stops the mixture from collapsing into a mush, the salsa supplies acidity and seasoning so you don’t need a heavy sauce, and melting cheese on top gives a quick, satisfying finish. The short bake softens the peppers while leaving them intact for easy handling — and any extra filling reheats or freezes well for lunches and fast dinners.

## Ingredients

### Cook the quinoa and preheat the oven

- 2/3 cup (dry) dry quinoa

### Prepare the peppers

- 6 medium bell peppers medium bell peppers

### Sauté the aromatics and spices

- 1 small onion + 2 cloves garlic small yellow onion + 2 garlic cloves
- 1 tablespoon olive oil
- 1 blend (see details) spice mix (1 tsp chili powder, 1 tsp ground cumin, 3/4 tsp kosher salt, 1/2 tsp black pepper)

### Make the filling

- 2 cups shredded cooked chicken cooked shredded chicken
- 1 cup (drained) black beans (drained)
- 1 cup corn (drained or frozen)
- 1/2 cup salsa
- 1 cup shredded shredded cheese

## Instructions

### 1. Cook the quinoa and preheat the oven

Rinse the dry quinoa in a fine sieve. In a small saucepan combine the dry quinoa with 1 1/4 cups (300 ml) water, bring to a boil, reduce to a simmer, cover and cook until water is absorbed (about 12–15 minutes). While the quinoa starts, preheat the oven to 375°F (190°C). Fluff cooked quinoa with a fork and set aside to cool slightly.

### 2. Prepare the peppers

Trim the tops of the medium bell peppers and remove seeds and membranes (reserve tops if you like for presentation). If any peppers won’t stand up, slice a thin bit off the bottom to level them. Place the prepared medium bell peppers upright in a 9x13-inch (or similar) baking dish.

### 3. Sauté the aromatics and spices

Heat the olive oil in a medium skillet over medium heat, add the small yellow onion + 2 garlic cloves and cook, stirring, until softened (about 3–4 minutes). Stir in the spice mix (1 tsp chili powder, 1 tsp ground cumin, 3/4 tsp kosher salt, 1/2 tsp black pepper) and cook 30–60 seconds until fragrant, then remove from heat.

### 4. Make the filling

In a large bowl combine the cooked quinoa, cooked shredded chicken, black beans (drained), corn (drained or frozen and thawed), salsa and the sautéed onion mixture. Reserve 1/4 cup of the shredded cheese for topping; stir the remaining 3/4 cup shredded cheese into the filling. Taste and adjust with a pinch more salt or pepper if needed.

### 5. Stuff and bake the peppers

Spoon the filling into each prepared medium bell pepper, filling to just below the rim (about 1 to 1¼ cups filling per pepper). Sprinkle the reserved 1/4 cup shredded cheese over the tops. Cover the baking dish loosely with foil and bake at 375°F (190°C) for 10 minutes, then remove the foil and bake 2–6 more minutes until peppers are tender and cheese is melted and lightly browned. Check the center of a pepper with an instant-read thermometer—the filling (including chicken) must reach 165°F / 74°C. If not yet 165°F, return to oven uncovered until it does. If tops brown too quickly, cover loosely with foil.

### 6. Rest, serve and store safely

Let the stuffed peppers rest about 2 minutes before serving so the filling sets. Serve warm. Refrigerate any leftovers in shallow airtight containers within 2 hours and use within 3–4 days; reheat to 165°F/74°C before eating. Makes 6 stuffed peppers; serve 1 stuffed bell pepper per serving (serves 6).

## Tips

### Measure quinoa yield

2/3 cup dry quinoa yields roughly 2 cups cooked, which is important to know when gauging total filling volume for six peppers.

### Level uneven bottoms

If a pepper won’t stand, slice a thin bit from the base — do this carefully so you don’t cut through to the cavity.

### Don’t overfill cavities

Fill peppers to just below the rim (about 1–1¼ cups each); excess filling can be baked separately in a small dish or saved for lunches.

### Check final temperature

Use an instant-read thermometer in the center of a stuffed pepper — the filling (including chicken) must reach 165°F/74°C for safety.

### Prevent watery filling

If your salsa is very runny, drain a little liquid or use a thicker salsa to avoid soggy peppers; cooked quinoa will absorb some moisture while resting.

## Variations and Substitutions

### Vegetarian swap

Omit the chicken and add 1 extra cup cooked quinoa or 1½ cups roasted diced sweet potato and an extra ½ cup black beans to preserve volume and texture.

### Dairy-free option

Replace the 1 cup shredded cheese with 1 cup dairy-free shredded cheese, or omit entirely and stir in 2–3 tablespoons nutritional yeast for a savory note.

### Use long-grain rice

Replace the 2/3 cup dry quinoa with 2/3 cup dry long-grain white rice cooked per package directions (about 1 1/3–1 1/2 cups water) to yield ~2 cups cooked rice.

### Turn up the heat

Stir in 1 finely diced jalapeño or 1–2 tablespoons chopped chipotle in adobo (to taste) with the sautéed onions for a smoky, spicy version.

### Mini pepper appetizer

Use small sweet mini peppers and halve the filling portions; bake uncovered 12–15 minutes until peppers are tender and filling hits 165°F.

## Notes

Using pre-cooked shredded chicken (rotisserie works well) keeps this recipe to ~30 minutes. Don’t overfill each medium bell pepper—leave a small border so the filling heats through; check the center reaches 165°F/74°C before serving.

### Storage and Make-Ahead

Cool leftovers to room temperature no more than 2 hours after cooking, then refrigerate in shallow airtight containers for 3–4 days. To freeze, wrap individual peppers or arrange in a freezer-safe container; they keep 2–3 months. Reheat from refrigerated or thawed state in a 350°F oven until an instant-read thermometer registers 165°F in the center; from frozen, add 10–15 minutes to the reheating time and cover to prevent over-browning.

### Serving Suggestions

Brighten the dish with a simple lime-crema (mix 1/2 cup Greek yogurt or sour cream with 1 tablespoon lime juice and a pinch of salt) spooned over each pepper. Serve with a crisp green salad or charred corn salad for contrast, and a wedge of lime or sliced avocado on the side; a light Mexican lager or a citrusy agua fresca pairs well.

## Frequently Asked Questions

### Can I make these ahead and bake later?

Yes — assemble the peppers, cover tightly, and refrigerate for up to 24 hours before baking; allow them to sit at room temperature 15–20 minutes before putting into the oven and then bake until filling reaches 165°F/74°C.

### What if my peppers aren’t standing upright?

Trim a thin slice from the bottom to level them, cutting just enough to create a flat surface; place them snugly in the baking dish so they support one another during baking.

### Can I use rotisserie chicken?

Absolutely — rotisserie chicken is a great shortcut and can be used in the same 2 cups shredded amount called for in the recipe.

### How can I avoid soggy peppers?

Use a thicker salsa or drain runny salsa slightly, sauté the onion until it releases excess moisture, and avoid overcooking the peppers — remove foil for the final minutes to evaporate surface moisture.

### How much filling should go into each pepper?

Aim for about 1 to 1¼ cups of filling per medium pepper; the recipe’s filling totals roughly 7½–8 cups, so it will fill six peppers with at most a tablespoon or two leftover.

### What’s the best way to reheat a single stuffed pepper?

Reheat in a 325–350°F oven for 12–18 minutes (covered to prevent drying), or microwave on medium power until the center reaches 165°F, checking with an instant-read thermometer.
