Mama Mia Mozzarella Meatloaves
with Balsamic Tomato Sauce, Roasted Potatoes & Broccoli
- Milk
- Wheat
While not everyone loves surprises, we can almost guarantee that anyone would be game for a treasure trove of gooey cheese hiding inside their mini meatloaf. And if that cheese just so happens to be melty mozzarella, even better! These stuffed loaves are baked, then topped with a rich and tangy balsamic tomato sauce and even more mozz. Oh, and did we mention there’s Italian-seasoned oven fries and roasted broccoli on the side? Mama mia!

Cooking Steps
• Adjust racks to top and middle positions and preheat oven to 450 degrees. Wash and dry produce. • Peel and mince or grate garlic. Dice potatoes into ½-inch pieces. Halve, peel, and thinly slice onion. Cut broccoli florets into bite-size pieces.
• In a large bowl, combine panko, garlic, 2 TBSP water, and 2 tsp Italian Seasoning (you’ll use the rest in the next step). (For 4 servings, use 4 TBSP water and 4 tsp Italian Seasoning.) • Add beef*, ¾ tsp salt (1½ tsp for 4), and pepper; mix to combine, then form into two 1-inch-tall loaves (four loaves for 4). Place on one side of a lightly oiled baking sheet.
• Toss potatoes on a second baking sheet with a large drizzle of olive oil, remaining Italian Seasoning, salt, and pepper. • Roast on top rack until browned and crisp, 20-25 minutes. • Place sheet with meatloaves on middle rack; roast for 10 minutes (you’ll add the broccoli then).
• Meanwhile, heat a drizzle of olive oil in a large pan over medium-high heat. Add onion; cook, stirring occasionally, until browned and softened, 8-10 minutes. • Add vinegar, 2 TBSP water, and 1 tsp sugar (2 tsp for 4 servings); cook, stirring, until onion is caramelized and jammy, 2-3 minutes. Stir in tomato paste and stock concentrate until combined. • Stir in ¼ cup water and bring to a simmer; cook until thickened, 1-2 minutes. Remove from heat and season with salt and pepper.
• Once meatloaves have roasted 10 minutes, remove sheet from oven. Carefully toss broccoli on empty side with a drizzle of olive oil, salt, and pepper. • Return to oven until meatloaves are cooked through and broccoli is browned and tender, 12-15 minutes more. TIP: If broccoli is done before meatloaves, remove from sheet and continue baking meatloaves.
• In the last 3-4 minutes of baking, top meatloaves with sauce and sprinkle with mozzarella. Return to oven until cheese melts. • Divide meatloaves, potatoes, and broccoli between plates and serve.
Ground Beef is fully cooked when internal temperature reaches 160°.
Customer reviews
Review summary
Updated on Sep 2026- Flavor: The balsamic tomato sauce is the star — tangy, rich, and unlike a typical meatloaf topping. Some found it too sweet or too sharp; using half the tomato paste and reducing the onion quantity keeps it balanced.
- Ease of prep: Timing three components across two oven racks takes some coordination, and a few found it more involved than expected. Reading through the steps before starting helps a lot.
- Suggestions: Use half the onion in the sauce — multiple customers found the full amount overwhelming. A few also preferred mashed potatoes over roasted, and one tip worth trying is roasting the broccoli on a separate pan from the meatloaves to avoid grease transfer.
- Leftovers: The recipe makes generous portions, with plenty of leftover veggies and sometimes a second serving of meatloaf 🎉.
- Sauce: If the sauce tastes too raw or thin, give it an extra minute or two on the heat; one customer also found using just half the tomato paste made it perfect for two servings.
Reviews from our home cooks
Too many onions in the sauce! And I only used 1/2 of the onion. It basically became an onion meatloaf.
Love this one so much! Shocked at how good the topping was on the meatloaf. Would get again.
The ketchup onion jam was interesting. Overall this was a great spin on a classic. I wasn't mad at it.
A well-balanced meal whose flavors were enjoyed by the whole family.
Too much in oven to fit at once for 4 person portion, took excessive time.
