• Baked Chili Rellenos with Ground Beef Recipe

If you love the flavor of a classic chili relleno but don’t want to deal with a pot of hot frying oil, this baked version is about to become your new favorite weeknight dinner. Charred poblano peppers get stuffed with a savory ground beef and cheese filling, then topped with a light, fluffy egg coating that bakes up golden and bubbly. It’s hearty, comforting, and a whole lot more wallet-friendly than the version you’d order at a restaurant.

What Is a Baked Chili Relleno?

A traditional chili relleno is a roasted poblano pepper stuffed with cheese, dipped in a fluffy egg batter, and fried until golden. It’s a beloved Mexican dish that’s rich, cheesy, and just a little smoky thanks to the charred pepper. Baking instead of frying gives you the same craveable flavor and texture without the mess or extra oil.

This version takes things a step further by turning the relleno into a full meal. Instead of just cheese, the peppers are packed with a seasoned ground beef and tomato filling, then baked under a blanket of whipped eggs and melted cheddar. The result is closer to a stuffed pepper casserole with all the personality of a classic relleno — perfect for feeding a hungry family without a ton of fuss.

Tips for Cooking and Prepping

#1: Char the peppers well for real flavor

Don’t rush the broiling step — letting the poblano skins blister and blacken in spots is what gives this dish its signature smoky depth. Turning them every 2-3 minutes ensures even charring on all sides.

#2: Let the peppers steam before peeling

Trapping the hot peppers in a covered bowl for 15 minutes loosens the skin so it practically slides off. Skipping this step makes peeling a frustrating, tearing mess.

#3: Buy ground beef on sale and freeze extra

Ground beef is often discounted in bulk packs at the grocery store — buy a larger quantity when it’s on sale, divide it into 1-pound portions, and freeze what you don’t need for this recipe to use in future meals.

#4: Drain the tomatoes thoroughly

Excess liquid from canned tomatoes will make your filling watery and can cause the stuffed peppers to fall apart in the baking dish, so give them a good shake in a strainer before adding them to the skillet.

#5: Dust the peppers with flour before stuffing

A light coating of flour inside each pepper helps the egg topping cling and set properly instead of sliding right off the sides.

#6: Whip the egg whites to true stiff peaks

This is what gives the topping its signature fluffy, souffle-like texture, so beat until the peaks hold their shape and don’t collapse when you lift the beaters.

Recipe Variations and Substitutes

This recipe is easy to customize based on what’s in your fridge or pantry. Swap the ground beef for ground turkey or chicken for a leaner option, or use pepper jack instead of Monterey Jack if you want extra heat. No poblanos at the store? Bell peppers work in a pinch, though you’ll lose some of the smoky flavor — just skip the broiling step and roast them briefly to soften instead.

What to Serve with Baked Chili Rellenos

These stuffed peppers are hearty enough to be the star of the plate, but a side of Mexican rice, black beans, or a simple green salad rounds out the meal nicely. Warm tortillas or tortilla chips are great for scooping up any extra filling, and a scoop of sour cream or fresh pico de gallo adds a cool, bright contrast to the rich, cheesy peppers.

Storing, Make-Ahead, and Freezing Tips

Leftovers keep well in an airtight container in the fridge for up to 3-4 days — just reheat gently in the oven or microwave until warmed through. You can prep the filling and roast the peppers a day ahead, then stuff and top with egg right before baking. For freezing, it’s best to freeze the stuffed peppers before adding the egg topping, since the whipped egg doesn’t thaw and reheat as well.

FAQs

Can I make baked chili rellenos ahead of time?

Yes, you can roast the peppers and prepare the beef filling up to a day in advance, then store them separately in the fridge. Stuff the peppers and whip the egg topping just before baking for the best texture.

Why did my egg topping deflate or turn watery?

This usually happens if the egg whites weren’t whipped to full stiff peaks or if they sat too long before baking. Whip them right before you’re ready to assemble and get the dish into the oven promptly.

Can I use a different pepper besides poblano?

Poblanos are traditional because they’re mild and have thick walls that hold up well to stuffing, but Anaheim peppers or even bell peppers can be substituted if poblanos aren’t available.

How do I know when the peppers are charred enough?

You’re looking for blistered, blackened patches across most of the pepper’s surface, which usually takes 8-10 minutes under a high broiler with regular turning. Don’t worry about getting every inch perfectly black — the steaming step finishes softening the skin.

Can I freeze leftover baked chili rellenos?

You can freeze them after baking, though the egg topping’s texture will soften upon reheating. For best results, freeze the beef-stuffed peppers before adding the egg and cheddar, then thaw, top, and bake fresh.

Baked Chili Rellenos with Ground Beef Recipe

Prep time: 30 min | Cook time: 30 min | Total time: 60 min | Servings: 6

Ingredients

For the Peppers

• 6 large poblano peppers

For the Filling

• 1 lb 90% lean ground beef
• 1 small yellow onion, finely diced
• 3 cloves garlic, minced
• 1 teaspoon ground cumin
• 1 teaspoon chili powder
• ½ teaspoon smoked paprika
• ½ teaspoon dried oregano
• ½ teaspoon salt, plus more to taste
• ¼ teaspoon black pepper
• 1 can (14.5 oz) diced tomatoes, drained well
• 1 cup shredded Monterey Jack cheese

For the Topping

• 4 large eggs, separated, room temperature
• 2 tablespoons all-purpose flour
• ¾ cup shredded sharp cheddar cheese
• Cooking spray or olive oil, for the baking dish

For Serving (Optional)

• Sour cream
• Pico de gallo
• Hot sauce
• Fresh cilantro

Instructions

1. Preheat your broiler to high. Place poblano peppers on a foil-lined baking sheet and broil for 8-10 minutes, turning every 2-3 minutes with tongs, until the skin is charred and blistered on all sides. Transfer to a large bowl, cover tightly with plastic wrap, and let steam for 15 minutes.
2. While the peppers steam, heat a drizzle of olive oil in a large skillet over medium-high heat. Add the diced onion and cook for 3-4 minutes until softened. Add the minced garlic and cook for 30 seconds until fragrant.
3. Add the ground beef to the skillet and cook, breaking it apart, for 7-8 minutes until fully browned. Drain any excess fat. Stir in the cumin, chili powder, smoked paprika, oregano, salt, and black pepper.
4. Add the well-drained diced tomatoes to the skillet and stir to combine. Cook for 2-3 minutes until most of the liquid has evaporated. Remove from heat and stir in the Monterey Jack cheese until melted. Let the filling cool for 5-10 minutes.
5. Preheat the oven to 375°F. Spray a 9×13-inch baking dish with cooking spray. Peel the charred skin off the steamed peppers. Carefully cut a slit lengthwise down each pepper and remove the seeds, keeping the pepper intact.
6. Lightly dust the inside of each pepper with about 1 teaspoon of flour. Stuff each pepper generously with the beef and cheese filling and arrange them seam-side up in the prepared baking dish.
7. Place the egg whites in a large clean bowl and beat with a hand mixer until stiff peaks form, about 3-4 minutes. In a small bowl, whisk the yolks with a pinch of salt. Gently fold the yolks into the whipped whites until just combined.
8. Spoon the egg mixture over each stuffed pepper, covering them completely. Sprinkle the shredded sharp cheddar cheese evenly over the top.
9. Bake at 375°F for 25-30 minutes until the egg coating is set and lightly golden and the cheese is bubbly. Let rest 5 minutes before serving. Top with sour cream, pico de gallo, and fresh cilantro if desired.

For an easy shortcut, look for pre-roasted or jarred whole green chiles at the store to save time on the broiling and peeling steps, though fresh poblanos will give you the best flavor and texture.
