Baked Beef Chili Relleno Recipe: Stuffed Pepper Surprise with Creamy Cheese Core

This baked beef chili relleno recipe transforms humble poblano peppers into showstopping stuffed peppers with a creamy, melty cheese center and rich chili filling. The secret lies in charring the peppers first—blackened skins add smoky depth while keeping the flesh tender—before stuffing them with slow-cooked beef and spiced chili. Every bite delivers that perfect contrast: crispy edges, creamy cheese, and hearty beef infused with cumin and chili powder.

The recipe balances tradition with convenience: while traditional versions require hours of simmering, this method uses a slow cooker for the beef filling, cutting prep time while maintaining restaurant-quality flavor. The chili sauce gets its signature richness from a blend of tomatoes, spices, and a touch of cocoa powder—just enough to deepen the flavor without overpowering the beef. And that gooey cheese center? It’s the star, melting into perfect pockets of tangy, creamy goodness when baked.

What makes this dish truly special is how it comes together: the peppers roast until tender, the filling stays moist and flavorful, and the cheese transforms into a luxurious, stretchy center. It’s the kind of meal that feels indulgent yet satisfying, perfect for weeknight dinners or special occasions. The aroma alone—smoky peppers, spiced beef, and melting cheese—will have everyone at the table asking for seconds.

Serve with a side of cilantro-lime rice or a dollop of sour cream to balance the heat, and you’ve got a complete, crowd-pleasing dish that’s as impressive as it is delicious. Ready to elevate your stuffed pepper game? Let’s get started.

Ingredients for baked beef chili relleno

Poblano peppers, spiced beef, and gooey cheese—this recipe delivers restaurant-quality stuffed peppers with minimal fuss.

The poblano peppers are the star, so pick firm, glossy ones—they should feel heavy for their size. Costco or local markets often have the freshest selection. Char them over an open flame or under the broiler until blackened all over; those smoky skins are what give this dish its signature depth. If you can't find poblanos, bell peppers in a pinch, but they won't have the same earthy sweetness. For the beef, 80% lean ground chuck gives the best flavor and texture—avoid leaner cuts or it'll dry out during slow cooking.

No chili powder? Mix 1 tbsp smoked paprika with 1 tsp cayenne for a similar kick. The cocoa powder might sound odd, but it's a secret weapon—just 1 tbsp deepens the chili flavor without adding sweetness. For the cheese, sharp cheddar and mild Monterey Jack create the perfect creamy-tangy combo. Pre-shredded cheese works, but freshly grated melts better and has less anti-caking agents. Swapping the tomato sauce for crushed tomatoes? Add 1 tsp sugar to balance acidity. And if you're short on time, pre-cooked ground beef from the deli section saves 20 minutes.

Stuffed peppers keep well—3-4 days in the fridge if stored in an airtight container. The cheese center stays gooey when reheated, so cover with foil and microwave 2-3 minutes. For make-ahead prep, assemble the peppers a day ahead and refrigerate uncovered so they don't get soggy. Freeze for up to 2 months by wrapping individually in foil. Leftovers? Slice the cheese core into cubes and serve as a snack with sour cream for dipping—trust me, it's delicious.

Step-by-step instructions for baked beef chili relleno

Transform simple ingredients into a showstopping stuffed pepper dish with layers of smoky beef and gooey cheese.

Preheat your oven's broiler to high. Arrange the 4 whole poblano peppers directly on the oven rack, leaving space between each. Broil for 8-10 minutes, turning occasionally, until the skins are completely charred and blistered all over. You'll see blackened patches and hear them sizzle—this is exactly what we want.

Here's the thing—charred peppers develop deeper flavor, but don't let them burn. If any pepper starts smoking excessively, move it to a different rack position. Once charred, transfer the peppers to a bowl, cover with a clean kitchen towel, and let them steam for 10 minutes. This makes the skins slip right off, revealing tender flesh underneath.

While the peppers steam, heat the 2 tablespoons olive oil in a large skillet over medium-high heat. Add the 1 whole yellow onion and cook for 5-6 minutes until softened and translucent. Add the 4 cloves minced garlic and cook for another 30 seconds until fragrant—this prevents the garlic from burning.

Push the onion mixture to one side of the pan and add the 1.5 pounds ground beef. Break it up with a wooden spoon as it cooks, breaking it into small pieces. Once the beef is browned and no longer pink, add the 2 tablespoons chili powder, 1 tablespoon ground cumin, 1 tablespoon cocoa powder, 1 teaspoon salt, and 0.5 teaspoon black pepper. Stir well to coat the beef evenly in the spices.

Pour in the 1.5 cups tomato sauce and 1 cup beef broth, scraping up any browned bits from the bottom of the pan. Bring to a simmer and cook for 8-10 minutes until the liquid reduces slightly and the flavors meld together. The filling should be thick enough to hold its shape when spooned.

Remove the skins from the poblano peppers by making a small slit at the stem end and gently pulling the skin off. Be careful not to tear the peppers—they should remain intact. Using a spoon, carefully hollow out the centers, leaving about ¼-inch thick walls. Chop the removed flesh and set it aside for later.

Stuff each pepper generously with the beef mixture, pressing down gently to fill them completely. Divide the 1.5 cups cheddar cheese and 1 cup monterey jack cheese evenly among the peppers, creating a creamy cheese core in each one. The cheese will melt and create that signature gooey center we're after.

Preheat your oven to 375°F. Place the stuffed peppers in a baking dish and pour any remaining beef mixture from the pan around them. This ensures every bite gets that rich, smoky flavor. Bake uncovered for 25-30 minutes until the peppers are tender and the cheese is fully melted and bubbly.

You'll know they're done when the tops are golden brown and the cheese has turned a beautiful golden hue. The peppers should feel soft when gently squeezed, and the filling should be heated through. If the cheese starts to brown too quickly, tent the dish with foil for the last 5 minutes of baking to prevent over-browning.

Let the stuffed peppers rest for 5-10 minutes before serving. This allows the juices to redistribute, ensuring each bite is packed with flavor. Serve immediately with your favorite toppings—sour cream, chopped cilantro, or a sprinkle of additional chili powder. The contrast of the creamy cheese core with the smoky beef filling is what makes this dish truly special.

This recipe serves 4 generous portions, perfect for a cozy dinner or a crowd-pleasing appetizer. The combination of charred peppers, spiced beef, and melted cheese creates a harmonious balance of textures and flavors that will leave everyone asking for seconds.

Health benefits of this dish

Protein Powerhouse

This dish packs a serious protein punch with 1.5 pounds of ground beef delivering about 40 grams of protein per serving. That’s nearly half of the recommended daily intake for most adults! The beef is lean enough to avoid excessive saturated fat while still providing all the essential amino acids your body needs for muscle repair and energy. 💪

Fiber-Rich Peppers

The poblano peppers add 3 grams of fiber per pepper, supporting digestion and keeping you full longer. Their charred skins also contain antioxidants like quercetin, which helps reduce inflammation. I always choose firm, glossy poblanos—they hold up better during charring and maintain their structure when stuffed.

Cheese Benefits

The combination of sharp cheddar and Monterey Jack provides 12 grams of calcium per serving, plus vitamin A for eye health. The cheese also contributes 8 grams of fat**, most of which are heart-healthy saturated fats when consumed in moderation. For a lighter option, reduce the cheese by ¼ cup without sacrificing flavor.
