Ingredients:
- 1 lb lean ground beef (90/10)
- 1 tbsp extra virgin olive oil
- 1 yellow onion, finely diced
- 3 cloves garlic, minced
- 24 oz marinara sauce
- 1 tsp dried oregano
- 1/2 tsp crushed red pepper flakes
- 1 tsp kosher salt
- 1/2 tsp black pepper
- 15 oz whole milk ricotta cheese
- 1 large egg
- 1/2 cup grated parmesan cheese
- 2 tbsp fresh parsley, chopped
- 1 lb spaghetti noodles
- 2 cups shredded whole-milk mozzarella
- 1 tbsp butter, melted
Instructions:
- Preheat your oven to 375°F (190°C).
- In a large skillet, heat olive oil over medium-high heat. Add ground beef and sear until a dark brown crust forms and no pink remains. Add diced onions and cook until translucent, then stir in minced garlic for 60 seconds.
- Stir in marinara sauce, oregano, red pepper flakes, salt, and pepper. Simmer on low for 10 minutes to reduce and intensify flavors.
- Boil spaghetti in salted water for 2 minutes less than the package al dente directions. Drain and toss with 1 tablespoon of melted butter.
- In a medium bowl, whisk the egg, then fold in ricotta, parmesan, and parsley until smooth.
- Spread 1/2 cup of meat sauce on the bottom of a 9x13 inch baking dish. Layer half of the cooked spaghetti, followed by the entire ricotta mixture, spreading it to the edges.
- Top with the remaining spaghetti, then the remaining meat sauce, ensuring all noodles are covered. Finish with an even layer of shredded mozzarella.
- Bake for 30 minutes until the cheese is melted and golden brown. Let rest for 10 minutes before slicing to set the layers.
