This Baked Beef Chiles Rellenos Casserole is sure to impress with its delightful blend of flavors and traditions! Step‑by‑Step Instructions for Baked Beef Chiles Rellenos Casserole Step 1: Prep Peppers Begin by roasting your poblano peppers over an open flame or under the broiler until they are nicely charred, about 10-15 minutes. Turn them frequently until the skin is blistered and blackened all around. Once they’re ready, transfer the peppers to a bowl, cover with a towel, and let them steam for about 10 minutes. This will soften the skin and make peeling easier. Step 2: Cook Meat While the peppers cool, heat a skillet over medium-high heat and add the ground beef. Cook the meat, breaking it apart with a spoon, until it’s browned and cooked through, around 7-10 minutes. Stir in cumin, garlic powder, salt, and pepper, letting the flavors meld for an additional 2 minutes. Drain any excess fat, ensuring a rich yet clean filling for your Baked Beef Chiles Rellenos Casserole. Step 3: Assemble Casserole Once the peppers have cooled, peel off the skin and carefully deseed them, keeping the peppers whole. Stuff each pepper generously with the savory beef mixture, allowing any excess to rest on top. Arrange the stuffed peppers in a baking dish, ensuring they fit snugly together to maintain their shape during baking, which will enhance the overall presentation of your casserole. Step 4: Prepare Egg Mixture In a medium bowl, whisk together the eggs until they are frothy. Then, fold in the shredded cheese for a creamy topping. Pour this egg and cheese mixture evenly over the stuffed peppers, ensuring each pepper gets well coated. This layer will provide that deliciously rich texture to your Baked Beef Chiles Rellenos Casserole. Step 5: Bake Cover the baking dish with foil and place it in a preheated oven at 350°F (175°C). Bake for about 30-35 minutes, or until the egg mixture is set and the casserole is bubbling slightly. The foil helps retain moisture, ensuring the casserole remains juicy and flavorful during the cooking process. Step 6: Finish Cooking After the initial baking time, carefully remove the foil to allow the top to brown. Continue baking for an additional 10-15 minutes until the top is golden and slightly crispy. This step adds a delightful contrast to the soft and cheesy interior of your Baked Beef Chiles Rellenos Casserole, making it visually appealing and tempting.
