This Traditional Poblano Casserole brings the rich, smoky flavors of roasted poblano peppers into a comforting, cheesy dish that's perfect for dinner. It's a great way to enjoy a taste of Mexican-inspired cuisine right from your kitchen.
The star of this dish is, of course, the poblano peppers, which when roasted, take on a deep, smoky flavor that's simply irresistible. Ground beef adds hearty substance to the casserole, absorbing all those wonderful spices and flavors. We use a duo of cheeses: Monterey Jack for its creamy meltability, and cheddar for its sharpness. The onions and garlic form the flavor base, while tomato sauce adds a bit of acidity to balance the richness. A touch of heavy cream makes the sauce velvety and indulgent. A sprinkle of cilantro at the end provides a fresh, herbal note that brightens the dish.
This casserole pairs beautifully with a light, crisp salad on the side to cut through the richness. Warm tortillas or a side of rice would also complement the flavors well.
First, you'll want to preheat your oven to 375°F (190°C). While that's warming up, start roasting the poblano peppers. If you have a gas stove, place them directly over the flame, using tongs to turn them until the skins are evenly charred. Alternatively, pop them under your broiler and keep a close eye. Once charred, put the peppers in a bowl and cover with plastic wrap to steam for about 10 minutes. This makes it easier to peel off the skins. Once they've cooled a bit, peel away that charred skin and remove the seeds. Set them aside for now.
Next, let's get the filling ready. Heat up a skillet over medium heat and add a tablespoon of olive oil. Toss in the diced onions and minced garlic, sautéing until the onions turn translucent. This usually takes about 5 minutes. Then, add the ground beef to the skillet, breaking it up with a spoon. Cook until it's nicely browned, and don't forget to drain any excess fat.
Now, season your beef with ground cumin, paprika, salt, and black pepper. Stir everything together and let it simmer for about 5 minutes to let the flavors meld. While that's happening, mix your Monterey Jack and cheddar cheeses in a bowl.
It's assembly time! Lay your roasted poblano peppers in a baking dish and stuff each one generously with the beef mixture. Sprinkle a handful of your cheese blend into each pepper. Once stuffed, pour the tomato sauce and heavy cream over the peppers. Top with the remaining cheese.
Bake this beauty uncovered for about 25-30 minutes, until the cheese is bubbly and golden. When it's done, garnish with fresh cilantro before serving.
