Let’s Make it Together
Preheat Your Oven and Prepare Your Dish: Start by preheating your oven to 350°F (175°C). Grease a large baking dish with olive oil for easy cleanup later.
Sauté the Aromatics: In a skillet over medium heat, add olive oil and sauté chopped onions until they become translucent and fragrant. Toss in minced garlic just before removing from heat.
Brown the Meat: Add ground beef to the skillet, breaking it apart with a spatula. Cook until browned, stirring occasionally. Drain excess fat if necessary for a lighter dish.
Add Marinara Sauce and Seasonings: Pour in marinara sauce along with Italian seasoning. Stir well until everything is coated with that luscious sauce.
Cook Spaghetti al Dente: Boil spaghetti according to package instructions until al dente—this prevents mushiness later when baking. Drain and set aside.
Combine Ingredients in Baking Dish: In a large bowl, mix cooked spaghetti with meat sauce mixture, beaten eggs, and half of both cheeses until evenly combined. Transfer everything into your greased baking dish.
Bake Until Golden Brown : Top with remaining cheddar and sprinkle parmesan cheese over everything. Bake in the oven for 30-40 minutes until bubbly and golden brown on top.
And voilà! Allow your masterpiece to cool slightly before serving—if you can resist! This baked spaghetti casserole is sure to be a hit at dinner tables everywhere!
Now that you’ve created this delightful dish, gather around your dining table with loved ones (or enjoy it solo while binge-watching your favorite show). Every mouthful brings comfort wrapped in nostalgia—a true crowd-pleaser that warms both hearts and bellies. Enjoy!
