The beef is the foundation—chuck roast delivers that tender, fall-apart texture after slow baking. Costco or Walmart usually carry pre-cubed chuck, which saves time. If you're buying a whole roast, ask the butcher to cube it for you. The tortillas should be medium-sized (about 8-10 inches) for the perfect balance of crispy and chewy. Mission or La Tortilla Factory brands work best—they char nicely and hold up during baking. For extra authenticity, look for corn tortillas, but flour tortillas work just as well if that's what you've got.
No chili powder? Mix 1 tbsp smoked paprika with 1 tsp cayenne for a similar kick. Fresh cumin seeds can be toasted and ground for a deeper flavor—just toast them in a dry pan for 30 seconds until fragrant. The tomato paste can be substituted with 2 cups crushed tomatoes, but you'll lose that concentrated umami punch. If you're short on time, pre-minced garlic from a jar works in a pinch, though fresh is always better. The beef broth should be low-sodium to avoid over-salting the dish—Swanson or Pacific Foods are reliable options.
This casserole tastes even better the next day, so make a double batch if you're feeding a crowd. Store leftovers covered in the fridge for up to 5 days, or freeze portions for 3 months. To reheat, cover with foil and bake at 350°F for 20-25 minutes. The tortillas crisp up beautifully when reheated—just a few minutes under the broiler brings back that golden crunch. For meal prep, assemble the casserole ahead of time and refrigerate uncovered for 1 hour before baking to let the flavors meld.

Step-by-step instructions for baked beef chili relleno casserole
Here's how to build a hearty, layered casserole where smoky beef meets crispy tortilla crunch.
🔥 Step 1: Sear and Season the Beef Chuck Roast
Heat a large skillet over medium-high heat and add the 2 tbsp olive oil. Once shimmering, add the 2 lb beef chuck roast in a single layer. Let it sear undisturbed for 4-5 minutes until a deep brown crust forms on all sides. This step builds incredible flavor through the Maillard reaction.
Remove the beef and place it in a large bowl. In the same skillet, add the 6 cloves minced garlic and 1 whole yellow onion diced small. Sauté for 3-4 minutes until softened and fragrant. Sprinkle in the 2 tbsp chili powder, 1.5 tbsp ground cumin, 1.5 tsp salt, and 0.5 tsp black pepper, stirring constantly for 30 seconds to toast the spices.
👨🍳 Step 2: Prepare the Chili Relleno Filling
Return the seared beef to the skillet with the aromatics and spices. Add the 0.5 cup tomato paste and 2 cups beef broth, stirring to combine. Bring to a simmer, then reduce heat to low and cook uncovered for 45-50 minutes until the beef is fork-tender and the sauce has thickened slightly. This creates the rich, smoky base for your casserole.
While the beef cooks, prepare the tortillas. Heat a clean skillet over medium heat and lightly brush each of the 12 whole flour tortillas with olive oil. Char them for 30 seconds per side until slightly crispy and spotted with black marks. This adds the signature crunch to your dish.
🥘 Step 3: Assemble the Layered Casserole
Preheat your oven to 375°F. In a 9x13-inch baking dish, spread half of the beef mixture evenly across the bottom. Arrange half of the charred tortillas on top, slightly overlapping. Sprinkle half of the 2 cups shredded Monterey Jack cheese over the tortillas, then repeat with the remaining beef mixture, tortillas, and cheese.
Cover the entire casserole with aluminum foil and bake for 25 minutes. This initial baking helps the cheese melt and the layers meld together without over-browning. Remove the foil and continue baking for another 10 minutes until the cheese is bubbly and golden on top.
🔪 Step 4: Finish with Creamy Toppings
Remove the casserole from the oven and let it rest for 5 minutes. Stir together the 0.5 cup sour cream and juice of 1 whole lime, then spread this mixture evenly over the top. Sprinkle with the 0.25 cup chopped fresh cilantro for a bright finish.
Return to the oven for 5-7 minutes just to warm through the toppings. The casserole should be bubbling with melted cheese and the tortillas should be crispy in spots. Let it rest for another 10 minutes before serving to allow the layers to set and the flavors to meld completely.
Pro Tips For Making Baked Beef Chili Relleno Casserole
- SEAR THE ROAST FIRST: I learned this the hard way—skipping the sear means a bland, gray center. Brown that chuck roast in a hot skillet with oil until it’s deep caramelized on all sides before slow-cooking. The crust locks in flavor and prevents the meat from drying out later.
- SOAK TORTILLAS IN BEER: Flour tortillas dry out fast when baked, turning into sad, stiff shells. Soak them in a mix of ½ cup beer (or warm broth) and 1 tablespoon cumin for 10 minutes before stuffing. The beer adds moisture and depth—yes, even if you’re not a beer drinker.
- DON’T OVERFILL THE TORTILLAS: Stuffing them too tightly means uneven cooking and a risk of bursting. Fill each tortilla with about ¼ cup of chili mixture, then fold and roll loosely—like a burrito, not a sausage. Tight rolls steam instead of crisp, and that’s a crime in this dish.
- BAKE LOW AND SLOW: This isn’t a 375°F casserole. Cover the dish with foil and bake at 325°F for the first 45 minutes to let the beef tenderize. Then uncover, crank to 375°F, and bake another 20 minutes. The two-stage heat keeps the tortillas from burning while the beef stays juicy. (I know, I know—patience isn’t your strong suit.)
Essential equipment for baked beef chili relleno casserole
Skillet Essentials
Start with a 12-inch cast iron skillet—like the Lodge Pre-Seasoned—for searing the beef and charring tortillas. Cast iron retains heat beautifully and creates that perfect crust.
For the beef, a heavy-bottomed Dutch oven (such as Le Creuset) works too if you prefer one-pot convenience during the simmering phase. 🔥
Oven Must-Haves
Your 9x13-inch baking dish needs to be oven-safe—Ceramic CorningWare or stainless steel are my top picks. Avoid dark-colored dishes (like black ceramic) as they can make the tortillas over-brown.
Line the dish with parchment paper for easy removal, but leave the edges uncovered so the cheese can get that golden crust.
Cheese Tools
Shred your own Monterey Jack cheese using a box grater for the freshest, most flavorful result. Pre-shredded cheese contains anti-caking agents that prevent proper melting. A microplane works great for the lime zest if you want to add a bright garnish.
Store-bought shredded cheese is fine in a pinch, but freshly shredded makes all the difference. 🧀
Tortilla Prep Kit
For charring tortillas, a small non-stick skillet (like All-Clad Stainless) works best—it heats up fast and gives you better control. Keep a pastry brush handy to lightly coat each tortilla with olive oil before charring.
A tortilla press isn’t necessary, but if you have one, it ensures even thickness for consistent charring.
Spice Toasters
Toast your cumin seeds and chili powder in a dry skillet over medium heat for 30 seconds to release their essential oils. This simple step deepens their flavor dramatically. A mortar and pestle works well for grinding toasted cumin seeds into a fine powder if you prefer a hands-on approach.
Store spices in airtight containers to preserve freshness—Weck jars are perfect for this.
Resting & Serving
After baking, let the casserole rest on a wire cooling rack for 10 minutes to prevent soggy tortillas. Use a serrated knife to slice through the crispy top—it glides through the cheese beautifully.
For serving, a wooden board adds rustic charm, while individual ceramic bowls keep portions warm. A lime wedge on the side lets guests add brightness to their taste. ✨

Frequently asked questions
Can I use ground beef instead of chuck roast?
Yes, but the texture will be different. Ground beef works in a pinch, but chuck roast gives you that tender, melt-in-your-mouth quality. If using ground beef, brown it thoroughly and drain excess fat first to avoid a greasy casserole. For best results, stick with chuck roast for that classic chili relleno richness.
How do I prevent soggy tortillas?
Char your tortillas just before assembling and bake the casserole uncovered for the last 10 minutes to crisp them up. Pro tip: Place a wire rack over a baking sheet, line with parchment, and bake the tortillas separately at 375°F for 3-4 minutes before layering. This keeps them crispy even after baking.
Can I make this casserole ahead of time?
Assemble it completely, cover tightly, and refrigerate for up to 24 hours before baking. For best results, let it sit at room temperature for 30 minutes before baking to ensure even cooking. Leftovers keep well for 4-5 days in the fridge—just reheat covered with foil at 350°F for 20 minutes.
What's the best way to reheat leftovers?
Cover with foil and reheat at 350°F for 20-25 minutes until bubbly. For extra crispiness, broil for 2-3 minutes at the end. If the tortillas get soggy, sprinkle with a little extra cheese and broil until melted. This method restores that perfect crunch while keeping the filling warm.
Can I make this vegetarian?
Yes, but you'll need to substitute the beef with portobello mushrooms or crumbled tempeh for texture. Use vegetable broth instead of beef broth and add 1 tbsp soy sauce for umami depth. The charred tortillas and cheese layers will still shine, but the flavor profile will be more earthy than meaty.
