Ingredients

  • 1 pound smoked sausage sliced into ¼-inch rounds
  • 1 large head broccoli cut into florets, about 2 c
  • 1 red bell pepper cut into 1-inch pieces
  • 1 yellow bell pepper cut into 1-inch pieces
  • 1 red onion sliced
  • 2 c cherry tomatoes halved
  • 4 tbsp olive oil
  • 1 tbsp Dijon mustard
  • 1 tsp garlic powder
  • 1 tsp Italian seasoning
  • 1 tsp paprika
  • ½ tsp salt
  • ¼ tsp black pepper
  • ¼ c grated Parmesan cheese optional

Instructions

Step 1: Prepare the Oven and Pan

  • Preheat the oven to 400°F.
  • Line an extra-large sheet pan, at least 21 x 15 inches, with parchment paper to help prevent sticking and make cleanup easier.

Step 2: Arrange the Sausage and Vegetables

  • Place the sliced smoked sausage, broccoli florets, red bell pepper, yellow bell pepper, sliced red onion, and halved cherry tomatoes on the prepared sheet pan.
  • Spread the ingredients evenly across the pan.

Step 3: Prepare the Seasoning Mixture

  • In a small bowl, whisk together the olive oil, Dijon mustard, garlic powder, Italian seasoning, paprika, salt, and black pepper until fully combined.

Step 4: Coat the Ingredients

  • Pour the seasoning mixture over the sausage and vegetables.
  • Using tongs or clean hands, toss until all ingredients are evenly coated with the oil and seasoning mixture.
  • Spread the sausage and vegetables into a single even layer, making sure the pan is not overcrowded.

Step 5: Roast

  • Place the sheet pan in the preheated oven.
  • Roast for 20 to 25 minutes, tossing once halfway through cooking, until the vegetables are tender and the sausage is heated through.

Step 6: Finish and Serve

  • Remove the sheet pan from the oven.
  • Sprinkle with grated Parmesan cheese, if desired.
  • Serve hot.
