Cheesy Beef Stuffed Potatoes with Broiled Mozzarella Step-by-step instructions

Before you start

Before you begin cooking, ensure your potatoes are already fully baked and cool enough to handle safely. Set up your workspace with a clean cutting board, a sharp knife, a sturdy spoon for hollowing, and a reliable meat thermometer.

Measure out the ground beef, tomato paste, tomato sauce, and shredded mozzarella cheese. Having all these components prepped and organized next to your stove will make the assembly process smooth, efficient, and completely stress-free.

Instructions

Hollowing the Potato Jackets

1. 1Scoop Out the Potato Flesh
   Use a spoon to gently hollow out the pre-baked potato halves, leaving a sturdy 1/4-inch border around the edges to create durable potato jackets. Save the scooped-out potato flesh for another use. Place the hollowed-out potato jackets into a cast-iron skillet, arranging them cut-side up so they are ready for the filling.
   Look for The jackets should hold their shape without tearing.
   Tip Be careful not to scoop too deep or the bottoms might tear during stuffing.

At the end of this initial phase, you should have four clean, sturdy potato halves arranged neatly in your cast-iron skillet.

The jackets should have a uniform 1/4-inch wall of potato flesh left inside, ensuring they are strong enough to support the heavy beef filling without tearing or collapsing. There should be no loose potato debris in the skillet, and the skins should feel slightly dry and ready to crisp up.

Cooking the Rich Tomato Beef Filling

2. 2Brown the Ground Beef
   Place the lean ground beef into a skillet over medium heat. Use a wooden spoon or spatula to break the meat apart into small crumbles as it cooks. Sauté for 5 to 6 minutes until the beef is fully browned and no longer pink, allowing it to cook in its own rendered fat.
   Look for The beef should be completely browned with no pink remaining.
   Tip Drain any excess grease from the skillet if necessary before adding the tomato products.
3. 3Simmer with Tomato Sauce
   Stir the tomato paste and tomato sauce into the browned ground beef. Reduce the heat to low and let the mixture simmer gently for 5 minutes, allowing the liquid to reduce into a rich, thick tomato beef filling. Ensure the beef reaches a safe internal temperature of 160°F (71°C) before removing the skillet from the heat source.
   Look for The filling should be thick and glossy, not watery.

   Tip A splash of beef broth can be added if the filling becomes too dry.

The completed beef filling should look thick, glossy, and deeply red from the tomato paste and sauce. The ground beef must be broken down into fine, uniform crumbles, thoroughly coated in the savory sauce, and showing no signs of excess liquid. It should smell intensely savory, and a quick check with a meat thermometer must register at least 160°F (71°C) to ensure it is fully cooked.

Assembling, Broiling, and Garnishing

4. 4Stuff the Potato Jackets
   Spoon the warm, savory tomato beef filling generously into the hollowed-out potato jackets resting in the cast-iron skillet. Distribute the meat mixture evenly among the four jackets, pressing down slightly with the back of the spoon to ensure they are packed tightly and completely filled.
   Look for Each potato jacket should be filled to the brim.
   Tip Keep the filling warm so the cheese melts faster under the broiler.
5. 5Top with Cheese and Broil
   Generously sprinkle the shredded mozzarella cheese over the beef-stuffed potato jackets, covering the filling completely. Place the cast-iron skillet under a preheated broiler set to high. Broil for 3 to 4 minutes until the mozzarella is completely melted, bubbling, and blistered with golden-brown spots. Garnish with finely chopped fresh parsley and serve immediately.
   Look for The cheese must be bubbling and blistered golden-brown.
   Tip Watch the broiler closely as cheese can burn very quickly.

The final checkpoint is reached when the mozzarella cheese is completely melted, bubbling vigorously, and dotted with deep golden-brown blistered spots. The potato jackets should be piping hot, and the fresh green parsley garnish should provide a vibrant contrast against the rich red filling and white cheese. A fork inserted into the center should easily glide through the gooey cheese and hot beef.

Common mistakes

One common mistake is scooping out too much potato flesh, which thins the walls and causes the jackets to break or leak during stuffing. Another frequent error is leaving the beef filling too watery; if the sauce is not simmered long enough to thicken, it will soak into the potato, making the skin soggy instead of crispy.

Lastly, avoid walking away from the broiler, as the high heat can turn perfect, golden-brown mozzarella into burnt, bitter charcoal in a matter of seconds.

How to tell it’s done

To guarantee both safety and deliciousness, the ground beef filling must be cooked to a safe internal temperature of 160°F (71°C) during the skillet simmering phase. The final doneness of the entire dish is indicated by the state of the mozzarella cheese.

It should be fully melted, stretching when pulled, and beautifully blistered with golden patches, while the potato skins underneath become wonderfully crisp and hot throughout.
