Instead of traditional spaghetti or spaghetti pie, make a Penne Pie. It's simple and quick to make and even more wonderful to eat.
1 lb. penne pasta
1 lb. ground beef, 85% lean
1 T. olive oil
1 medium yellow onion, chopped
3 large eggs
2 c. marinara sauce
1 c. whole milk ricotta cheese
½ c. grated Parmesan cheese, plus 2 T., divided
2 T. minced flat leaf parsley
1 c. shredded Mozzarella cheese
1 t. salt
¼ t. freshly ground black pepper
Preheat oven to 350 degrees. Grease a 9 x 3 inch cake pan.
Bring a large pot of salted water to a boil. Add penne pasta; cook 3-4 minutes less than the package directions, so that it is very al dente. Drain, but reserve a small amount of pasta water.
In a large skillet over medium-high heat, brown the beef. Pour off excess grease. Season with salt and pepper.Transfer to a paper towel-lined plate to soak up more grease. Wipe the skillet clean with a paper towel. Heat olive oil in the skillet over medium heat; sauté onions until translucent, about 4-5 minutes; remove from heat.
In a large bowl, whisk eggs, marinara sauce, ricotta cheese, ½ c. Parmesan cheese, parsley, salt, pepper and 2 T. reserved pasta water; add cooked penne, beef and onions. Toss to coat. Transfer to the prepared cake pan. Top with Mozzarella cheese; sprinkle with remaining Parmesan cheese.
Bake 25 - 30 minutes, until cheese is bubbling and golden brown. Let sit 5 minutes, then cut into wedges and serve.
