1️⃣ Preheat the oven: Preheat your oven to 375°F (190°C). Grease a 9×13-inch baking dish and set aside.

2️⃣ Cook the beef: In a large skillet, heat olive oil over medium heat. Add the ground beef and cook until browned, breaking it into crumbles with a spoon. Use a slotted spoon to remove the beef and set it aside.

3️⃣ Sauté the aromatics: In the same skillet, add the chopped onion and minced garlic. Sauté for 3-4 minutes until the onion is translucent and fragrant.

4️⃣ Cook the vegetables: Add the diced potatoes, carrots, and celery to the skillet. Cook for about 5 minutes, stirring occasionally to lightly brown the vegetables.

5️⃣ Combine ingredients: Stir in the corn kernels, cooked ground beef, diced tomatoes (with their juices), and beef broth. Season the mixture with salt, black pepper, thyme, and rosemary. Mix well to combine.

6️⃣ Assemble the bake: Transfer the beef and vegetable mixture to the prepared baking dish. Spread it out evenly. Cover the dish tightly with aluminum foil.

7️⃣ Bake: Bake in the preheated oven for 30 minutes, or until the vegetables are tender.

8️⃣ Add cheese topping: Remove the foil and sprinkle the shredded cheddar cheese evenly over the top. Return the dish to the oven and bake for an additional 10-15 minutes, or until the cheese is bubbly and golden brown.

9️⃣ Rest and serve: Allow the bake to rest for 5 minutes before serving. This helps the flavors meld together and makes serving easier. Enjoy warm with crusty bread or a side salad!
