Ingredients

• For the Beef & Aromatics:
• 1 ½ lbs lean ground beef (85/15 or 90/10)
• 1 large yellow onion, chopped
• 3-4 cloves garlic, minced
• 1 tablespoon olive oil (if needed for browning beef)
• ½ teaspoon salt
• ¼ teaspoon black pepper
• For the Vegetables:
• 4 cups mixed vegetables (e.g., carrots, peas, green beans, corn – fresh or frozen, no need to thaw frozen)
• 1 medium bell pepper (any color), chopped (optional, for extra crunch and color)
• For the Sauce & Binder (No Canned Soup!):
• ¼ cup all-purpose flour
• 2 tablespoons tomato paste
• 2 cups beef broth or stock
• 1 cup milk or half-and-half
• 1 teaspoon dried Italian herbs (or a mix of dried thyme, oregano, basil)
• ½ teaspoon paprika
• Salt and black pepper to taste
• For the Topping:
• 1 ½ cups shredded cheddar cheese (or a cheddar blend)
• ¼ cup plain breadcrumbs (optional, for extra crunch)

Directions

1. Prep & Preheat
   1. Preheat your oven to 375°F (190°C).
   2. Lightly grease a 9x13-inch baking dish with cooking spray or butter.
   3. If using fresh vegetables, chop them now. Measure out all your other ingredients so they're ready to go.
2. Brown the Beef & Aromatics
   1. In a large skillet or sauté pan over medium-high heat, brown the ground beef, breaking it up with a spoon as it cooks. Cook until no pink remains.
   2. If there's a lot of excess fat, carefully drain it from the pan.
   3. Add the chopped onion to the skillet with the beef. Cook for 5-7 minutes, stirring occasionally, until the onion softens.
   4. Stir in the minced garlic, salt, and pepper. Cook for another minute until fragrant.
3. Build the Sauce in the Pan
   1. Sprinkle the flour evenly over the beef and onion mixture in the skillet. Stir constantly for 1-2 minutes to cook out the raw flour taste. This creates a simple roux that will thicken your sauce.
   2. Stir in the tomato paste until it's well combined with the beef mixture.
   3. Gradually whisk in the beef broth, a little at a time, until the mixture is smooth and begins to thicken.
   4. Next, gradually whisk in the milk or half-and-half until the sauce is smooth.
   5. Stir in the dried Italian herbs and paprika. Bring the sauce to a gentle simmer, stirring, until it thickens to a consistency that coats the back of a spoon. Taste and adjust salt and pepper as needed.
4. Add Vegetables & Assemble the Casserole
   1. Stir the mixed vegetables (fresh or frozen) and chopped bell pepper (if using) into the sauce in the skillet. If using frozen vegetables, there's no need to thaw them first; just break up any clumps.
   2. Pour the entire beef and vegetable mixture into your prepared 9x13-inch baking dish. Use a spoon or spatula to spread it into an even layer.
5. Top & Bake
   1. Evenly sprinkle the shredded cheddar cheese over the top of the casserole. If desired, sprinkle the breadcrumbs over the cheese for an extra crispy crust.
   2. Bake for 30-35 minutes, or until the casserole is bubbling around the edges and the cheese on top is melted and golden brown. If the top is browning too quickly, you can loosely tent it with foil.
6. Rest & Serve
   1. Once baked, remove the casserole dish from the oven and let it rest for 10-15 minutes. This important step allows the sauce to set, making it easier to scoop and preventing it from being too watery.
   2. Scoop generous portions into bowls. Garnish with fresh chopped parsley if you like. Serve warm with your favorite simple sides!
