Instructions

Sear the Sausages: Heat olive oil in a large skillet over medium-high heat. Add the sausages and cook until browned on all sides, about 5 minutes. Remove and set aside.

Caramelize the Onions: In the same pan, add the onions and cook until soft and golden, about 8 minutes. Stir occasionally to prevent burning.

Sauté the Garlic and Spices: Add the garlic, red pepper flakes, and Italian seasoning. Sauté for 30 seconds, just until fragrant.

Make the Sauce: Stir in the tomato paste and cook for 1 minute to deepen the flavor. Add the crushed tomatoes, season with salt and pepper, and let the sauce simmer for 10 minutes.

Simmer with the Sausages: Return the sausages to the pan, nestling them into the sauce. Cover and let everything simmer on low heat for 15-20 minutes, or until the sausages are fully cooked and infused with the sauce.

Finish with Fresh Herbs: Just before serving, stir in fresh basil or parsley for a burst of flavor.

Serve and Enjoy: Spoon over pasta, polenta, or tuck into a crusty roll for an irresistible sandwich.
