A flavorful and creamy pasta dish with a Cajun twist, perfect for a quick and satisfying dinner.
Heat the olive oil in a large skillet over medium heat.
Ensure the skillet is hot before adding the sausage to achieve a good sear.
Add the smoked sausage slices and cook until browned, about 4 minutes.
Stir occasionally to ensure even browning.
Add the diced onion and cook until softened, about 3 minutes.
Lower the heat slightly to avoid burning the onion.
Stir in the minced garlic and Cajun seasoning, cooking for 30 seconds until fragrant.
Be careful not to burn the garlic as it can turn bitter.
Pour in the diced tomatoes, heavy cream, and 1 cup of water. Bring to a simmer.
Stir well to combine the ingredients evenly.
Add the penne pasta and stir to coat. Cover and cook until the pasta is tender, about 15 minutes.
Stir occasionally to prevent the pasta from sticking to the bottom.
Stir in half of the cheddar cheese until melted.
Adding the cheese gradually helps it melt smoothly.
Transfer the mixture to an oven-safe dish, top with the remaining cheese, and broil until bubbly and golden.
Keep an eye on the broiler to avoid burning the cheese.
Garnish with chopped scallions and serve warm.
Serve immediately for the best texture and flavor.
