One-Pan Impossible Pizza Pie with a Crispy Baking-Mix Crust Step-by-step instructions

Before you start

Before the pan goes on the heat, get everything within arm's reach. Take the ground beef out of the refrigerator and keep it there only while the pan heats, never longer than 30 minutes. Shred the mozzarella if using a block, measure the pizza sauce, seasonings, baking mix and milk, and set the eggs on the counter for a few minutes so the batter mixes smoothly.

Butter the deep pan now or right before layering, whichever fits the flow, and put a rimmed baking sheet on a rack in the lower-middle of the kitchen. Preheat the oven to 400°F (200°C) partway through the beef step so it reaches temperature by the time the layers are built. Have the colander ready in the sink for draining the fat, and a wire rack standing by for the rest.

Instructions

Brown the beef and thicken the sauce

1. 1Brown the seasoned beef
   Set a 10-inch deep cast-iron skillet or deep-dish pan over medium-high heat and add the ground beef, breaking it into small crumbles with a spatula as it cooks. Sprinkle in the Italian seasoning, garlic powder and kosher salt. Keep cooking and stirring until no pink remains, about 6 to 8 minutes, so every crumble picks up color.
   Look for The crumbles look deeply browned with no pink spots left anywhere in the pan.
   Safe temperature 160°F (71°C) internal temperature (ground meat)
   Tip Let the beef sit undisturbed for a minute at a time so it browns instead of steaming.
2. 2Simmer the sauce into the beef
   Drain the fat through a colander, then return the beef to the pan. Pour in the pizza sauce and stir well, scraping up any browned bits stuck to the bottom. Let it bubble gently for 2 to 3 minutes over medium heat until the sauce clings to the meat and the mixture looks thick and glossy rather than watery.
   Look for The mixture mounds on the spatula with almost no liquid pooling around it.
   Tip A thicker sauce keeps the crust from turning soggy during baking.

At the end of this phase, the beef is deeply browned with no pink anywhere, drained of fat, and coated in a pizza sauce that has simmered down until it clings to the meat rather than pooling around it. The mixture should mound on the spatula and smell savory and tomatoey, with the garlic and herbs clearly present.

Check two things before moving on: the pan bottom is scraped clean of browned bits, and there is no thin liquid spreading when the filling is pushed aside. If the sauce still looks loose, give it another minute of simmering, because a thick filling is what keeps the crust crisp later.

Layer the filling and pour the batter

3. 3Build the layers
   Lower the oven rack to the center position and heat the oven to 400°F (200°C). Grease the pan generously with butter. Spread half of the shredded mozzarella in an even layer on the bottom, then spoon the saucy beef over it and spread it edge to edge. Finish with the remaining mozzarella scattered across the beef.
   Look for You can see three distinct bands: cheese, beef, cheese.
   Tip Cheese against the pan helps the crust release cleanly at serving time.
4. 4Whisk the batter
   In a large mixing bowl, combine the all-purpose baking mix, whole milk and eggs. Whisk for a good 30 seconds, longer than feels necessary, until the batter looks completely smooth with no dry pockets of mix clinging to the bottom or sides of the bowl. It should pour like thin pancake batter.
   Look for The batter streams off the whisk in a smooth ribbon, not in lumpy drops.
   Tip A well-mixed batter bakes into an even crust with no dense streaks.
5. 5Pour and top with pepperoni
   Slowly pour the batter over the layered filling, starting in the center and letting it drift outward so the layers stay undisturbed. Do not stir. Arrange the pepperoni slices in a single layer on top, letting a few overlap slightly, and set the pan on a rimmed baking sheet to catch any bubbling over.
   Look for The batter settles into the gaps around the filling and the pepperoni still floats on top.
   Tip Pouring low and slow keeps the cheese layer hidden beneath the crust.

This phase ends with the pan holding three clean bands: mozzarella against the buttered bottom, saucy beef spread edge to edge, and more mozzarella on top, all sealed under a smooth batter with pepperoni floating on the surface. The batter should have been whisked until it pours in a ribbon with no lumps, and it should have been poured low and slow so the layers stayed put. Check that no dry pockets of baking mix remain in the bowl and that the pepperoni still sits on top rather than sinking. Set the pan on the rimmed baking sheet now, before it goes into the oven, so any bubbling is caught.

Bake, rest and slice the pie

6. 6Bake until golden and set
   Bake on the center rack for 30 to 35 minutes, rotating the pan once halfway through. The pie is ready when the crust is deep golden brown, the center no longer looks wet when gently pressed with a fingertip, and the pepperoni cups glisten with rendered fat. The edges will pull slightly away from the pan.
   Look for A knife inserted near the center comes out clean, with no wet batter on it.
   Tip If the top browns too fast, tent it loosely with foil for the last 10 minutes.
7. 7Rest, slice and lift
   Move the pan to a wire rack and let the pie rest for 10 minutes. During this time the crust firms up and the layers settle, so slices hold together instead of collapsing. Run a thin spatula around the edge, cut into six wedges, and lift the first slice slowly to show off the cheese pull and the thick layers beneath.
   Look for The first slice stands tall with defined beef, cheese and crust layers.
   Tip A pie server slid fully under the slice keeps the crust from cracking on the way up.

After the bake and the rest, the pie comes out with a deep golden crust that has pulled slightly from the sides of the pan, glistening pepperoni cups on top, and a center that feels set under a gentle press. A knife inserted near the middle should come out clean. After the 10-minute rest, the first wedge should lift on a spatula with a long cheese pull and stand tall with distinct beef, cheese and crust layers. If the slice slumps or the crust looks pale, the pie needed more time; if everything holds, the pan is ready for the table.

Common mistakes

The most common mistake is rushing the beef browning. Pale, steamed crumbles taste flat, so give the meat real contact with the hot pan and let it sit undisturbed in stretches. The second is draining badly: fat left behind makes the filling greasy, so drain thoroughly before the sauce goes in.

Third, a watery sauce: pizza sauce straight onto the beef needs those 2 to 3 simmering minutes to thicken, or the crust underneath turns soggy. Fourth, under-whisking the batter, which leaves dense streaks of dry mix in the finished crust; whisk a full 30 seconds. Finally, slicing too soon: cutting within five minutes of the oven means slumped, collapsing wedges, while a 10-minute rest gives tall, defined layers.

How to tell it’s done

Three signs say the pie is done. First, the crust: deep golden brown across the top, with the edges pulled slightly away from the pan and the surface dry to a gentle fingertip press, never wet or shiny in the center. Second, the knife test: a thin blade inserted near the middle comes out clean, with no wet batter clinging to it.

Third, the pepperoni: the slices glisten with rendered fat and the cheese beneath them bubbles at the edges. The beef was already cooked to 160°F (71°C) before layering, so the bake only needs to set the crust and heat the layers through. When in doubt, give the pie five more minutes; an extra bake deepens the crust color without hurting the filling.
