Cheesy Pizza Hamburger Pie is a baked ground beef dish where seasoned extra-lean beef forms the crust of a 9-inch pie, topped with sautéed mushrooms and green onions, fresh green pepper and Roma tomato, dried herbs, and melted non-fat mozzarella. The honest reason to make it: one pan, 55 minutes, and you get protein, vegetables, and cheese in every slice without ordering out. It comes in at 260 calories and 28 grams of protein per serving, which is hard to beat for a weeknight dinner.
The technique that matters
The meat crust is the whole structure of this dish, so how you press it matters. Pack the beef mixture firmly and evenly up the sides of the pie pan — at least three-quarters of an inch thick — or the walls will slump inward during baking and you’ll lose the pocket that holds the toppings. Use the back of a spoon or damp fingers to smooth the surface. The second thing worth doing carefully is wringing out the soaked rye bread thoroughly before mixing it in. Too much moisture in the meat base and the crust steams instead of browning, leaving the bottom soft and difficult to slice cleanly. Squeeze the bread until it feels almost dry, then crumble it in. Those two steps — firm, even pressing and a dry bread binder — are what give you clean, holdable slices at the table.
Common problems and fixes
- Watery toppings make the crust soggy: Mushrooms release a lot of liquid. Sauté them until that liquid has fully evaporated before adding them to the pie — not just until they look cooked. A wet mushroom layer will soak into the meat crust and prevent it from setting properly.
- Cheese browns before the beef is cooked through: Ground beef in a thick pie shell needs to reach 160°F (71°C) at the center. If the cheese is darkening before 35 minutes are up, tent the pan loosely with foil for the last 10 minutes. Use an instant-read thermometer to confirm the meat is done — skip the garnish, not worth the extra dish — and check the center of the base, not the edge.
- Pie sticks to the pan and falls apart when serving: Cooking spray alone sometimes isn’t enough, especially with lean beef. Line the bottom of the pie pan with a small round of parchment after spraying, then spray again. The 5-minute rest after baking is also non-negotiable — cutting too soon means the structure hasn’t set and slices will crumble.
- Meat crust shrinks away from the sides: Extra-lean beef has less fat to hold it in place, so it can pull back during baking and leave a gap. Pressing the beef slightly above the rim of the pan before baking accounts for that shrinkage and keeps the sides intact.
- Tomato slices make the top wet: Roma tomatoes are drier than beefsteak varieties, but if yours are very ripe, blot the slices with a paper towel before laying them on. This keeps the herb and cheese layer from sliding off and gives the top a cleaner finish.

Equipment
Ingredients
- 1 slice rye bread - about 1 oz / 30g, soaked in water, wrung out thoroughly, and crumbled (discard the bread crusts if very hard)
- 1 ounce egg substitute - 30ml, or 1 small egg white
- 1 large Roma tomato - sliced thin
- 1 teaspoon olive oil cooking spray - for coating pie pan and sauté pan
Instructions
- Preheat the oven to 375°F / 190°C (170°C fan-forced).
- In a medium bowl, combine the ground beef, crumbled rye bread (squeezed until almost dry), egg substitute, garlic powder, pepper, and salt. Mix with your hands until just combined — do not overwork.1 pound ground beef, 1 slice rye bread, 1 ounce egg substitute, 1/8 teaspoon garlic powder, 1 pinch ground black pepper, 1/4 teaspoon kosher salt
- Coat a 9-inch (23cm) pie pan with cooking spray. Press the beef mixture firmly and evenly across the bottom and up the sides of the pan to form a crust at least ¾-inch (2cm) thick. Use damp fingers or the back of a spoon to smooth the surface.1 teaspoon olive oil cooking spray
- Coat a non-stick sauté pan with cooking spray and place over medium heat. Sauté the green onions and mushrooms for 3-4 minutes until softened and lightly golden.2 stalks green onions, 2 large mushrooms, 1 teaspoon olive oil cooking spray
- Spread the sautéed vegetables evenly over the beef crust. Scatter the diced green pepper over the top, then arrange the Roma tomato slices in overlapping rings. Sprinkle with the dried basil and oregano, then top evenly with the shredded mozzarella.1/2 small green pepper, 1 large Roma tomato, 1/4 teaspoon dried basil, 1/4 teaspoon dried oregano, 1/2 cup mozzarella cheese
- Bake for 35 minutes until the cheese is golden brown and the internal temperature of the beef crust reaches 160°F / 71°C.
- Allow the pie to rest in the pan for 5 minutes — this firms up the crust and makes slicing easier. Run a thin spatula around the edges to loosen, then carefully slide or lift the pie onto a serving plate. Cut into 4 wedges.
Notes
Nutrition
Your questions, answered
Can I use regular ground beef instead of extra-lean?
You can, but expect more fat to render out during baking and pool in the bottom of the pan. Blot it with a paper towel through the oven rack before adding toppings, or the crust will sit in grease and the base will be greasy rather than firm.
How do I know the meat crust is fully cooked?
Use an instant-read thermometer inserted into the thickest part of the beef base — it needs to read 160°F (71°C). The 35-minute bake time is a reliable guide, but oven temperatures vary, so checking with a thermometer is the only way to be certain.
Can I make this ahead and reheat it?
Yes. Bake it fully, cool completely, then refrigerate for up to 3 days. Reheat individual slices in a 350°F oven for about 10 minutes, or in a covered skillet over medium-low heat — this keeps the crust from drying out better than a microwave does.
What can I substitute for egg substitute?
One small whole egg works as a direct swap. The egg substitute is there purely as a binder, so any liquid egg product or a lightly beaten whole egg in roughly the same volume will do the same job.
Can I swap the ground beef for ground turkey?
Ground turkey works well here and keeps the calorie count similar. If you use it, note that ground poultry must reach 165°F (74°C) at the center — check with a thermometer since turkey can look done before it actually is.
Does this dish provide enough for a complete meal on its own?
For most adults, one or two slices delivers a solid protein serving alongside the vegetable toppings, so it stands on its own as a main. If you want more volume, a simple green salad or a side of steamed broccoli rounds it out without adding much prep time.
