Keto Italian Sausage & Broccolini Skillet with Tomato Butter Sauce

There’s something incredibly comforting about a skillet of sizzling sausage and veggies bubbling away in a tomato butter sauce. We came up with this Keto Italian Sausage & Broccolini Skillet on a weeknight when we wanted something hearty, rich, and deeply flavorful—but still low-carb and easy to make. It instantly became a household favorite, and now we turn to it whenever we want a taste of rustic Italian cooking with minimal cleanup.

The mild bitterness of broccolini pairs beautifully with the sweet acidity of cherry tomatoes, especially when softened in a garlicky butter sauce. Add in golden-browned sausage—spicy or mild depending on your mood—and the flavors come together in one of those magical ways that feel far more complex than the effort it takes to make. A final touch of shaved Parmesan and fresh basil takes everything over the top.

This dish is a keto dream. It’s naturally low in carbs, rich in flavor, and offers a solid serving of healthy fats and protein in each bite. Plus, it’s made entirely in one pan, which makes it perfect for busy weeknights when we want something satisfying and delicious without spending hours in the kitchen.

When served hot from the skillet with a simple side of cauliflower mash or all on its own, this dish brings Italian comfort straight to the table—no pasta required.
