Preheat Oven:
Set your oven to 350°F (175°C).
Cook Vegetables:
Heat olive oil in a skillet over medium heat. Add the chopped onions and green peppers, and sauté until they are soft and tender.
Mix Ingredients:
In a large bowl, combine the cooked onions and peppers with the ground beef, whole milk, mushrooms (if using), bread crumbs, egg, garlic powder, onion powder, Adobo seasoning, salt, pepper, and Worcestershire sauce. Mix well with your hands until everything is evenly incorporated.
Prepare Loaf Pan:
Grease a loaf pan with a little oil or non-stick spray. Place half of the meat mixture into the pan, pressing to form an even layer.
Add Cheese:
Lay four slices of cheese over the meat layer.
Add Remaining Meat:
Cover the cheese with the remaining meat mixture, pressing gently to seal the edges.
Bake:
Place the loaf pan in the oven and bake for 30 minutes.
Add More Cheese:
Remove the pan from the oven, add the remaining four slices of cheese on top, and return to the oven. Bake for another 10-15 minutes, or until the cheese is melted and slightly crispy.
Rest and Serve:
Let the meatloaf rest for a few minutes after baking before slicing. This helps the juices settle and makes the meatloaf easier to cut. Serve warm slices of your delicious cheesesteak meatloaf and enjoy!
Notes:
If you need to make this meatloaf gluten-free, simply substitute the regular bread crumbs for a gluten-free alternative and ensure your Worcestershire sauce is labeled gluten-free. With these tweaks, you’ll have a delicious, gluten-free meatloaf that everyone can savor!
