I remember the first time I needed something that felt like a family meal but was also forgiving for a nervous cook, so I adapted an old meatloaf into a simple meatloaf casserole that bakes flat in a dish and slices like a breeze, the kind of thing I make when I want comfort without too much fuss.
Why You’ll Love It
This meatloaf casserole is perfect for first timers because it keeps the classic flavors of meatloaf but skips the shaping and wobble, making it easy to mix, press into a pan, and bake. It works for weeknight dinners, casual potlucks, or a cozy Sunday supper, and picky eaters usually warm to the familiar tomato glaze and tender, well-seasoned slices.
Serves 6
Prep Time: 20 minutes |
Cook Time: 60 minutes |
Total Time: 80 minutes
Ingredients
- 1 1/4 lb lean ground beef (about 565 g)
- 1/2 cup plain breadcrumbs (50 g)
- 1 small yellow onion, finely chopped (about 3/4 cup)
- 1 large egg
- 1/2 cup milk
- 2 cloves garlic, minced
- 2 tablespoons Worcestershire sauce
- 1 teaspoon kosher salt
- 1/2 teaspoon freshly ground black pepper
- 1 teaspoon dried thyme or Italian seasoning
- 1/2 cup ketchup for topping
- 2 tablespoons brown sugar
- 1 teaspoon Dijon mustard
- 2 tablespoons chopped fresh parsley for garnish
Instructions
- Preheat your oven to 350 F and lightly grease a 9×13 inch rectangular baking dish.
- In a large bowl, combine the ground beef, breadcrumbs, chopped onion, egg, milk, minced garlic, Worcestershire sauce, salt, pepper, and dried thyme, gently mixing until just combined.
- Transfer the mixture into the prepared baking dish and press it down into an even layer so it fills the pan smoothly.
- In a small bowl, stir together the ketchup, brown sugar, and Dijon mustard until smooth, then spread the glaze evenly over the top of the meat.
- Bake uncovered for 55 to 60 minutes, until the center reaches a safe temperature and the glaze is set and slightly caramelized at the edges.
- Let the casserole rest 10 minutes before slicing into squares, garnish with chopped parsley, and serve warm.
Recipe Variations
- Cheesy Top: Sprinkle 1 cup shredded cheddar over the glaze during the last 10 minutes of baking for a melty finish.
- Turkey or Chicken Version: Substitute ground turkey or chicken for a leaner casserole, add an extra tablespoon of oil for moisture.
- Veggie Boost: Stir in 1 cup finely diced carrots and bell pepper into the meat mixture for added texture and nutrition.
- Gluten Free: Use gluten free breadcrumbs or crushed gluten free crackers to keep the dish wheat free.
Make Ahead: You can mix the meat mixture and transfer it to the baking dish, cover tightly, and refrigerate up to 24 hours before baking. The glaze can be mixed and stored separately in the fridge for 2 days. After baking, leftovers keep well refrigerated for 3 to 4 days and can be reheated in a low oven or sliced cold for sandwiches.
Frequently Asked Questions
Can I use a different ground meat blend for meatloaf casserole
Yes, you can use ground pork, turkey, or a mix of beef and pork; adjust fat content slightly and add a tablespoon of oil if using very lean meat to keep it moist
How can I tell when the casserole is fully cooked without a thermometer
The edges will pull slightly from the pan and the glaze will be set and glossy, but using a thermometer is the most reliable way to ensure the center reaches 160 F for ground beef
Can I freeze this meatloaf casserole
Yes, bake first and cool completely, then wrap pieces tightly or place in a freezer container for up to 3 months, thaw overnight in the fridge and reheat in the oven until warmed through
