Brown Sausage and Sauté Veggies
Heat the large skillet over medium‑high. Add the Italian ground sausage, breaking it up with a meat chopper or spoon. Once browned (about 5‑6 minutes), add the diced bell pepper and half an onion. Cook until the vegetables are softened, about 4 minutes.

Prepare Alfredo Sauce
In a clean medium skillet over medium‑high, melt 1 stick (8 tbsp) butter. Sprinkle ¼ cup flour over the butter and whisk for 1 minute to form a roux. Slowly whisk in 16 oz heavy whipping cream, stirring constantly until the mixture thickens (about 3‑4 minutes). Reduce heat to medium‑low, whisk in 1 cup shredded Parmesan until melted, then season with a pinch of black pepper and a dash of garlic powder. Remove from heat.
Time: PT10M
Temperature: Medium‑Low
Combine Spaghetti with Alfredo
Pour the Alfredo sauce over the drained spaghetti in the pot. Toss until every strand is evenly coated. Taste and add a little extra salt or garlic powder if needed.
Time: PT2M
