📖 Instructions

1. Before you even think about cooking, get everything ready. Dice your onion and bell peppers into small, even pieces. Mince the garlic. Open your can of diced tomatoes and corn, and drain the corn well. Trust me, 'mise en place' makes everything smoother, especially when you're in a hurry.
2. Place a large (10-12 inch) oven-safe skillet over medium-high heat. A cast-iron skillet works wonders here for even heat distribution. Add a tablespoon of olive oil or your preferred cooking oil. Once the oil shimmers, add the ground beef. Break it up with a wooden spoon or spatula as it cooks.
3. Cook the ground beef for about 5-7 minutes, stirring occasionally, until it's completely browned and no pink remains. This step is key for flavor! Once browned, carefully drain any excess grease from the skillet. You can tilt the pan and use a spoon or paper towels to soak it up.
4. Reduce the heat to medium. Add the diced onion and bell peppers to the skillet with the cooked beef. Sauté for 5-7 minutes, or until the vegetables have softened slightly and the onion is translucent. Don't rush this part; tender veggies add so much to the dish.
5. Stir in the minced garlic, chili powder, cumin, smoked paprika, and a good pinch of salt and black pepper. Cook for an additional minute, stirring constantly, until the spices are fragrant. This 'blooming' of the spices really intensifies their flavor.
6. Pour in the diced tomatoes (undrained, so you get all that lovely juice!) and the drained corn. Stir everything together well, scraping up any browned bits from the bottom of the pan. Bring the mixture to a gentle simmer.
7. Reduce the heat to low, cover the skillet, and let it simmer for 10-15 minutes. This allows all the flavors to meld together beautifully and ensures the vegetables are perfectly tender. Stir occasionally to prevent sticking.
8. While the skillet is simmering, if your oven isn't already, preheat it to 375°F (190°C). This is for melting the cheese at the end.
9. After simmering, remove the lid. Taste the mixture and adjust seasonings if needed. Maybe it needs a little more salt, or a dash more chili powder? Now, sprinkle the shredded cheddar and Monterey Jack cheese evenly over the top of the beef and vegetable mixture.
10. Transfer the skillet to the preheated oven. Bake for 5-10 minutes, or until the cheese is completely melted and bubbly, and slightly golden in spots. Keep a close eye on it to prevent burning the cheese!
11. Carefully remove the hot skillet from the oven using oven mitts. Let it rest for a few minutes before serving. This allows the cheese to set slightly and prevents burned tongues. Garnish with fresh cilantro, a dollop of sour cream, or sliced jalapeños if you like a little extra kick! Serve hot with your favorite taco fixings.
