Step‑by‑Step Instructions for Baked Beef Chiles Rellenos Casserole
Step 1: Prepare Peppers
Start by roasting your poblano peppers either directly on an open flame or under the broiler for about 5–10 minutes, until the skin is charred and blistered. Keep an eye on them and turn occasionally to ensure even charring. Once done, transfer them to a bowl, cover with plastic wrap, and let them steam for about 10 minutes, which will make peeling easier.
Step 2: Cook Filling
In a large skillet, heat a tablespoon of oil over medium heat and sauté one finely chopped onion and two minced garlic cloves for 2–3 minutes, until softened. Add one pound of ground beef to the pan, seasoning with cumin, paprika, salt, and pepper. Cook for about 5–7 minutes, breaking apart the meat, until browned and cooked through. Remove from heat and let cool slightly.
Step 3: Stuff Peppers
Once the roasted poblano peppers are cool enough to handle, peel off the charred skin and make a slit along the side to remove seeds. Carefully stuff each pepper with the seasoned ground beef mixture, filling them generously so they’re packed and flavorful. Arrange the stuffed peppers in a greased 9×13 inch baking dish, standing them upright for an appealing presentation.
Step 4: Make Topping
In a separate bowl, whisk together four eggs and one cup of shredded cheese until well combined. This mixture will act as a creamy topping for your Baked Beef Chiles Rellenos Casserole. Pour the egg and cheese blend evenly over the stuffed peppers in the baking dish, allowing it to drench the filling for added richness and cohesion in the bake.
Step 5: Bake
Preheat your oven to 350°F (175°C) and place the casserole in the oven. Bake for approximately 30–40 minutes, or until the egg is set and the top is golden brown and bubbly. Keep an eye on it towards the end to prevent over-browning while achieving that perfect golden crust that adds to the comforting visuals of this Baked Beef Chiles Rellenos Casserole.
Step 6: Serve
Once baked to perfection, remove the casserole from the oven and let it cool for about 10 minutes before slicing. This will help the layers hold together beautifully. Serve warm, garnished with fresh cilantro if desired, and prepare to enjoy a delightful meal that showcases the rich flavors of the Baked Beef Chiles Rellenos Casserole!
