Ingredients for baked beef chili relleno
Crispy tortillas, gooey cheese, and slow-cooked beef—this is where Mexican comfort meets restaurant-quality texture contrast.
| Ingredient | Amount | Notes |
|---|---|---|
| Poblano Peppers 🌶️ | 4 whole | Charred over flame, seeds removed |
| Ground Beef 🥩 | 1 ½ lb | 80% lean for best texture |
| Yellow Onions 🧅 | 1 whole | Diced, medium size preferred |
| Garlic Cloves 🧄 | 6 cloves | Freshly minced for aroma |
| Canned Tomato Sauce 🍅 | 1 cup | San Marzano preferred |
| Chicken Broth 💧 | 1 cup | Low-sodium for balance |
| Chili Powder 🌶️ | 2 tbsp | Medium heat preferred |
| Ground Cumin 🌿 | 1 tbsp | Toasted for depth |
| Salt 🧂 | 1 ½ tsp | Diamond Crystal preferred |
| Black Pepper 🌶️ | ½ tsp | Freshly ground |
| Shredded Monterey Jack Cheese 🧀 | 2 cups | Freshly shredded |
| Large Flour Tortillas 🌯 | 4 whole | 6-inch diameter |
| Vegetable Oil 🫒 | ½ cup | For frying tortillas |

The poblano peppers are non-negotiable here. Look for firm, deep green peppers at the grocery store—avoid any with soft spots. Char them over a gas flame (or grill) until blackened, then peel off the skin under running water. Trader Joe's and Mexican markets often carry the best quality. For the beef, 80% lean ground chuck gives you that perfect fat-to-meat ratio—too lean and it dries out. The tortillas? Mission brand is my go-to for consistent quality, but any sturdy 6-inch flour tortilla works.
No poblano peppers? Two jalapeños in a pinch, but they'll add heat. Short on ground beef? Substitute with diced flank steak—just make sure to slice it thin. The chili powder can be swapped for 1 tbsp each of smoked paprika and regular chili powder if you're missing one. Fresh cumin seeds? Toast them in a dry pan for 30 seconds before grinding for next-level flavor. The tortillas need to be fried until golden—don't rush this step or they'll stay soggy. And if you can't find Monterey Jack, Oaxaca cheese melts beautifully too.
The chili filling keeps well in the fridge for 4 days—make extra if you can. Fry the tortillas fresh before baking (they lose crispiness if made ahead), but you can prep the filling in advance. Once assembled, these rellenos should bake for 15-20 minutes—watch closely to avoid over-browning. Serve immediately with sour cream on the side—the cheese pull is best when piping hot. Leftovers? Reheat in a 350°F oven for 10 minutes to restore crispiness.

Step-by-step instructions for baked beef chili relleno
Here's how to create the perfect balance of crispy tortilla shells and gooey cheese fusion.
Char and Prepare the Poblano Peppers
Hold each of the 4 whole poblano peppers over a gas flame or under a broiler, turning frequently, until the skin blackens all over—this should take about 8-10 minutes. The peppers will smell smoky and the skin will be completely charred. Place them in a bowl, cover with plastic wrap, and let steam for 10 minutes.
Once cooled enough to handle, peel off the blackened skin by rubbing the peppers with your fingers or a paper towel. Make a small slit at the stem end and gently squeeze out the seeds and membranes. You want clean, empty peppers ready to be stuffed. If any skin remains, use a knife to scrape it away—this ensures a smooth texture when filled.
Sauté the Aromatics and Brown the Beef
Heat 0.5 cup vegetable oil in a large skillet over medium-high heat. Add the diced yellow onions and cook for 5-6 minutes until softened and translucent. Add the minced garlic cloves and cook for another 30 seconds until fragrant—don't let the garlic burn, or it will turn bitter.
Push the onions and garlic to one side of the pan and add the 1.5 lb ground beef in small batches. Break it up with a wooden spoon as it browns, about 5-6 minutes total. Once fully browned, drain any excess fat from the pan, leaving behind the rich, meaty juices that will flavor your filling.
Build the Chili Filling
Return the browned beef to the pan and stir in the 2 tbsp chili powder, 1 tbsp ground cumin, 1.5 tsp salt, and 0.5 tsp black pepper. Cook for 1 minute to toast the spices and deepen their flavors. Then add the 1 cup canned tomato sauce and 1 cup chicken broth, stirring to combine.
Simmer the mixture over medium-low heat for 10-12 minutes until slightly thickened. The filling should be moist but not soupy—it should coat the back of a spoon. Taste and adjust seasoning if needed, adding a pinch more salt or chili powder if desired. Let the filling cool slightly before stuffing the peppers.
Stuff and Assemble the Rellenos
Preheat your oven to 375°F. Working quickly, fill each poblano pepper with about 1 cup of the chili filling, pressing gently to compact it. Place the stuffed peppers upright in a baking dish, spacing them about 1 inch apart. Top each with a large flour tortilla, pressing the tortilla down lightly to adhere to the pepper.
Sprinkle the 2 cups shredded Monterey Jack cheese evenly over the tortillas, covering them completely. The cheese will melt and create a gooey layer between the tortilla and pepper, ensuring that crispy texture you're after. Bake for 20-25 minutes until the cheese is fully melted and the tortillas are golden brown and crispy.
Serve with Sour Cream
Remove the rellenos from the oven and let them rest for 5 minutes before serving. The cheese will continue to set slightly during this time, making it easier to handle. Cut each stuffed pepper in half lengthwise to reveal the gooey cheese and crispy tortilla fusion.
Serve immediately with the 0.5 cup sour cream on the side for dipping. Each bite should offer a perfect contrast of textures—crispy tortilla, tender poblano, and creamy cheese. The chili filling should be flavorful and well-seasoned, tying everything together in a satisfying fusion of Mexican and Tex-Mex influences.
Pro Tips For Making Baked Beef Chili Relleno
- CHAR THE PEPPERS RIGHT: Roast the poblano peppers directly over a gas flame (or under a broiler) until blackened all over—don’t just rely on the oven. The char adds smoky depth that no amount of sauce can replicate, and it’s the thing that makes this dish taste like a proper Mexican restaurant version. I used to peel them under cold water, but now I just let them sit in a bowl for 10 minutes—no scrubbing needed.
- BROWN THE BEEF FIRST: Skip the pre-cooked shortcut and sear the ground beef in batches over medium-high heat until it’s deeply browned, not just pink. That crust locks in flavor and prevents the filling from tasting like raw meat later. After burning three batches of chili relleno with bland filling, I finally learned: high heat, small batches, and don’t stir too often.
- SALT THE ONIONS BEFORE COOKING: Toss the diced yellow onions with a pinch of salt and let them sit for 5 minutes before adding them to the pan. This draws out moisture, so they caramelize faster and add sweetness without turning mushy. I was skeptical until I tried it—now I do it every time, even when I’m in a hurry.
- USE A MIX OF SAUCES: Swap half the canned tomato sauce for a quick blend of fire-roasted crushed tomatoes and a splash of beef broth. The broth thins the filling just enough to prevent a dry relleno, while the fire-roasted tomatoes add a smoky punch without extra prep. It’s the upgrade I skip when I’m lazy, but the dish is noticeably better when I don’t.
Make-ahead tips for leftovers
Prep the Filling Ahead
Make the beef chili filling up to 3 days ahead—it tastes even better after the flavors meld. Store it in an airtight container in the fridge. When ready to assemble, just reheat it gently in a saucepan over medium-low heat for 5-7 minutes, stirring occasionally. This keeps the filling moist and flavorful, so it doesn’t dry out when stuffed into the peppers. 💫
Fry Tortillas Early
Fry the tortillas right before baking to maintain their crispiness. However, you can prep them in advance by frying them, letting them cool completely, then storing them in a single layer between parchment paper in an airtight container for up to 24 hours. Reheat them in a 350°F oven for 3-4 minutes before assembling the rellenos to restore that perfect crunch. 🌯
Assemble Without Stress
Stuff the peppers and assemble the rellenos 1 hour before baking—this gives the filling time to settle and the cheese to melt evenly. Cover the assembled dish loosely with aluminum foil and refrigerate until ready to bake. The cold start ensures the cheese melts smoothly and the tortillas stay crispy, not soggy. 🧀
Bake at the Right Time
Bake the rellenos no more than 1 hour before serving—the cheese stays gooey and the tortillas retain their crunch. If you need to hold them, keep them in a 200°F oven on a wire rack for up to 30 minutes. For a quick reheat, pop them in a 375°F oven for 5-7 minutes to restore that golden, crispy exterior. 🔥
Serve with Sides Ready
Prep your sides like rice, beans, or sour cream while the rellenos bake to streamline serving. Warm the rice in a 350°F oven for 10 minutes or heat beans on the stovetop for 3-4 minutes. This way, everything is ready at the same time, and you can focus on enjoying the meal instead of last-minute prep. ✨

Frequently asked questions
Can I use regular bell peppers instead of poblanos?
While you can substitute bell peppers, poblanos are essential for that authentic smoky depth and tender texture. If you must use bell peppers, choose large green ones and char them just like poblanos for the best flavor. The filling will still work, but the dish will lack that signature Mexican complexity.
How do I fix soggy tortillas after baking?
Soggy tortillas usually mean the cheese didn't melt properly or the tortillas weren't crispy enough before baking. For next time, fry the tortillas until golden brown and place them on a wire rack to cool completely before assembling. Also, ensure the cheese is evenly distributed and fully melted during baking.
Can I make this dish ahead of time?
Yes! Prepare the beef chili filling up to 3 days ahead and store it in an airtight container. Reheat gently before stuffing the peppers. However, fry the tortillas fresh before baking to maintain crispiness. Assemble the rellenos 1 hour before baking and keep them refrigerated until ready to bake.
What's the best way to reheat leftovers?
Reheat leftovers in a 375°F oven for 10-12 minutes to restore crispiness. Place them on a wire rack to avoid sogginess. For microwave reheating, cover with a damp paper towel and heat in 30-second intervals until warmed through. The cheese may lose some crispiness but will still be delicious.
Can I make this dish vegetarian?
Replace the ground beef with a hearty mix of black beans, lentils, and diced mushrooms. Sauté the mushrooms with onions and garlic, then combine with the beans, spices, and broth. The texture will be slightly different but still packed with flavor. For extra protein, add crumbled tofu or tempeh.
