Tips

  • Use fresh Brussels sprouts. I love a good recipe that utilizes frozen veggies, but I do not think frozen Brussels would work well in this dish. Brussels are often frozen whole and are quite soft once defrosted and do not sauté well, in my experience.
  • Make this Brussels sprouts pasta recipe fresh. Meal prep is great, but not all recipes work as a make ahead option. I find this recipe is best enjoyed right after it’s made.
  • If you REALLY want to make it ahead. You can do a little prep ahead so you can streamline dinner a bit more. Simply cook the Brussels sprouts part of the dish up to a day ahead and reheat it in a pan while you cook the pasta. Once pasta is done cooking, add it to the reheated Brussels sprouts.

Suggested Adaptations

  • Want to make this dairy-free? You can leave out the parmesan from this Brussels sprouts pasta. Just make sure to taste and add more salt and pepper to adjust the seasoning.
  • Up the more flavor. Top the final dish with some toasted chopped walnuts or almonds. You could also make some garlic breadcrumbs and sprinkle those on top for some extra flavor and texture.
  • Use any pasta you like for this recipe –whole wheat, gluten free, or bean-based pastas will work well.
  • If you don’t need this pasta to be vegetarian, chicken or pork Italian sausage would be a great addition. You could also add some cooked chicken or shrimp.
