1-Making Hamburger Sausage Pie: is a fun process that starts with preheating your oven and ends with a tasty meal ready to serve. Begin by setting your oven to 350 degrees F and placing the rack in the center for even baking. This temperature works well to cook the ingredients thoroughly without drying them out, ensuring a moist and flavorful pie.

2-First, prepare your 9-10 inch springform pan: by lining the bottom with parchment paper, securing the ring, and greasing it with vegetable shortening or butter. In a large skillet over medium-high heat, brown 1 pound ground beef and 1/2 pound Italian sweet sausage with 1 tablespoon of the extra virgin olive oil until fully cooked, then drain and reserve the cooking liquid after skimming off fat. This step builds the base flavor, so don’t skip saving that liquid for later.

3-Next, in the same skillet over medium heat, add the remaining 2 tablespoons extra virgin olive oil and sauté 1 large sweet onion (diced into half-inch pieces, about 2 1/2 cups), 1 large green bell pepper (diced into half-inch pieces, about 2 cups), 1 teaspoon dry basil, 1 teaspoon dry oregano, 1 teaspoon kosher salt, 1/2 teaspoon freshly ground black pepper, and a pinch of red pepper flakes for about 4 minutes until they are tender-crisp.

4-Building the Layers: Then, add 2 tablespoons fresh garlic, minced, and cook for 1 minute before making space in the skillet to add 2 tablespoons tomato paste and cook for another minute. Stir in 2 tablespoons of the reserved meat liquid and the cooked meat mixture, then set it aside to cool slightly. In a separate bowl, whisk together 3 large eggs, 1 cup Greek full fat yogurt, 1/2 teaspoon kosher salt, 1 1/2 teaspoons baking powder, and 1/2 cup all-purpose flour until smooth to create the batter.

5-Pour half of the batter into the prepared pan and spread it evenly. Layer half of the meat mixture on top, sprinkle with 1/2 cup grated Parmesan cheese, and add 1/4 pound sliced provolone cheese. Top with the remaining meat mixture, then mix 1 large bunch of diced scallions (about 1 cup) and 1 1/2 cups shredded mozzarella cheese into the remaining batter and pour it over everything. Place the pan on a foil-lined sheet pan to catch any drips and bake for 45 minutes, with an optional 1-2 minutes under the broiler to brown the top.

6-After baking, let the pie rest for 10 minutes in the pan, then run a knife around the edges to loosen and remove the ring before slicing into 8 pieces. Serve it warm for the best experience, and remember, the total prep time is about 30 minutes with cooking taking around 1 hour.
