Spaghetti Pie

Step 1
Preheat the oven to 350 degrees F (175 degrees C). Grease a 10-inch pie plate or springform pan.

Step 2
Bring a large pot of water to a boil. Stir in 1 tablespoon oil and 2 teaspoons salt. Cook spaghetti in boiling water-oil mixture, stirring occasionally, until tender yet firm to the bite, about 12 minutes. Drain, then transfer to a large bowl.

Step 3
Mix eggs, Parmesan cheese, and butter into spaghetti until well combined. Press and shape into the prepared pie plate to form crust. Spread cottage cheese over crust.

Step 4
Heat 1 tablespoon oil in a large skillet over medium-high heat. Cook and stir beef, onion, and green pepper until beef is thoroughly browned and crumbly, 5 to 7 minutes. Mix in tomatoes, tomato paste, sugar, oregano, 1/2 teaspoon salt, and garlic powder until combined. Spread mixture over cottage cheese.

Step 5
Bake uncovered in the preheated oven for 30 minutes. Sprinkle with mozzarella cheese and continue baking until cheese is bubbly and beginning to brown, 5 to 10 minutes more.
