Please read my disclosure.These hearty, spicy, vegetarian stuffed poblano peppers with quinoa and corn are a Southwestern classic and take less than an hour to make! Earthy and sweet, rich and filling, this is a delicious, simple recipe that’s a real crowd-pleaser.

If you’ve never had vegetarian stuffed poblano peppers before, now is the time to try them! They are mild and just slightly sweet, and hold up really well when roasted – which makes them perfect for stuffing. They’re one of my favorite ingredients to use in quick and tasty dinners!

I’m a huge fan of Southwestern and Mexican flavors, so between the fresh corn, southwestern spices, poblanos and melted, gooey, Pepperjack cheese, I knew this recipe would be a hit. It’s vegetarian and gluten-free, and with just a few substitutions can be made vegan as well.

This recipe looks super complex to make, but it’s actually really easy! It’ll be ready (from start to finish) in just 45 minutes. It’s kid-friendly too — if you have littler kids I just recommend cutting it up for them before serving to make it much easier for them to eat with a fork.

How to Make These Vegetarian Stuffed Poblano Peppers, Step By Step
Adjust an oven rack to the middle position and preheat oven to 425 degrees. Wash and dry all produce. Halve poblanos through stem, then remove seeds and ribs. Dice tomato. Trim and thinly slice scallions, separating whites from greens. Wash quinoa. Zest lime until you have 1 tsp; quarter lime.

Bring vegetable stock and a large pinch of salt to a boil in a small, lidded pot. Once boiling, add quinoa, cover, and reduce heat to low. Simmer until quinoa is tender and water has evaporated, 15-20 minutes. (TIP: If not all water evaporates, drain excess.)
While quinoa cooks, rub poblano halves with oil (about 1 tsp per pepper – 4 tsp total); season with salt and pepper. Place on a baking sheet cut sides down. Roast on middle rack until tender, about 20 minutes. Meanwhile, in a small bowl, combine greek yogurt or sour cream, lime zest, a squeeze of lime juice, and 2 tsp water. Season with salt and pepper.

Drain corn and pat dry with paper towels. Heat a drizzle of oil (about 1 tsp) in a large, oven-safe pan over high heat. Add corn and cook, stirring occasionally, until slightly charred, 4-5 minutes. (TIP: If corn begins to pop, cover pan.)
Reduce heat to medium and add tomato, scallion whites, and Southwest Spice blend or taco seasoning. Cook, stirring occasionally, until tomato breaks down, about 2 minutes. Season with salt and pepper.

Stir cooked quinoa into pan with veggies; season with salt and pepper.
Once poblanos are done roasting, stuff each with as much of the grain mixture as will fit. Place in pan with remaining grain mixture, nestling each poblano half in the grains. (TIP: If your pan isn’t ovenproof, transfer mixture to a small baking dish and arrange stuffed poblanos in there.) Sprinkle evenly with cheese. Heat broiler to high.


Transfer pan with stuffed peppers to middle rack of oven. Broil until cheese is melted and lightly browned, 2-3 minutes.

Remove from oven, then top with lime crema and scallion greens. Divide among plates. Serve with any remaining lime wedges on the side for squeezing over.

What Makes These Vegetarian Stuffed Poblano Peppers Healthy?
These peppers are packed with protein and fiber, making them a filling, vegetarian friendly, and nutritious meal. Poblano peppers are rich in Vitamin A, C, Potassium and fiber, while the quinoa provides whole grains and protein. Sweet corn provides lutein (good for your eyes!), B vitamins, and potassium, along with a healthy dose of fiber and the pepperjack cheese gives this recipe decadence while also adding protein.
Can you make this recipe gluten free or vegan?
Good news! This recipe already is gluten free! To make it vegan, either omit the cheese and Greek yogurt/sour cream, or use vegan substitutes for both.
How Hot Are Poblano Peppers?
Poblano peppers actually have a pretty mild taste, and are about 2-8 times less spicy than jalapeno peppers, but spicier than bell peppers. On the Scoville heat unit scale, poblanos score 1,000-1,500 units vs. jalapenos which score at 2,500-8,000 units vs. bell peppers which have a score of 0. This makes them the perfect pepper for this recipe because they have enough flavor without being too spicy!

Anjali, These are an amazingly delicious stuffed pepper. I made pretty much exactly as written in recipe. Did not have poblano peppers however I grew giant marconi peppers which resemble poblanos and used those with excellent results. I would stay away from bell peppers but would substitute cubanelles as well. My husband went nuts over these! The lime crema drizzled over finished peppers adds just the perfect hint of lime and tang! Thank you for this keeper!!!
Yay!! I’m so happy to hear that you all loved this recipe! Thanks for letting me know! 🙂
This was super delicious! And healthy. Thanks for the recipe!!

So delicious! Added chopped green olives and queso fresco at the end of mixing in the rice(didn’t have quinoa ) served with refried beans! She’s a keeper🤗
Yay!!! So happy to hear that Cynthia! 🙂
