How to Make Roasted Italian Sausage, Potato, Tomato Casserole

Follow our traditional Roman technique for perfect results

Ingredients

  • 2-3 tablespoons olive oil
  • 2 medium Yukon Gold or red potatoes, each cut into quarters
  • 2 tomatoes, cut in half
  • 1-2 garlic cloves, cut in half
  • 1 large red onion, cut into 4 chunks
  • 2 red bell peppers, cut into 4 large pieces
  • 4 excellent quality Italian sausages, uncooked
  • Salt and freshly ground black pepper, to taste
  • Fresh rosemary or oregano sprigs (optional, for roasting)
  • Fresh parsley, chopped (optional, for garnish)

The Preparation

  1. Preheat your oven to 400°F (200°C) and prepare a large baking sheet or roasting pan.
  2. In a spacious mixing bowl, combine the quartered potatoes, halved tomatoes, halved garlic cloves, red onion chunks, and red bell pepper pieces. Drizzle generously with olive oil, then season with salt and freshly ground black pepper. Gently toss all the vegetables to ensure they are evenly coated.
  3. Arrange the seasoned vegetables in a single layer on the prepared baking sheet, leaving some gaps for the sausages.
  4. Place the four uncooked Italian sausages evenly among the vegetables on the baking sheet. If desired, tuck in a few fresh rosemary or oregano sprigs for added aroma.
  5. Roast in the preheated oven for 30 minutes.
  6. After 30 minutes, carefully flip the sausages and gently toss the vegetables to ensure even browning and cooking. Continue roasting for another 10-15 minutes, or until the sausages are thoroughly cooked (reaching an internal temperature of 160°F/71°C) and the vegetables are tender and beautifully caramelized.
  7. Remove the casserole from the oven, allow it to rest for a few minutes before serving hot. Garnish with freshly chopped parsley, if desired, for a final touch of freshness.

Expert Tips for Best Results

Texture

For perfectly crisp potatoes and nicely browned sausages, avoid overcrowding the baking sheet. Give each ingredient room to breathe and roast, rather than steam. A preheated baking sheet can also enhance crispiness.

Aroma

To deepen the aroma, use high-quality extra virgin olive oil and fresh herbs like rosemary or oregano. A pinch of red pepper flakes added with the vegetables can also introduce a subtle, warming heat that complements the sausages.

Preservation

Store any leftover casserole in an airtight container in the refrigerator for up to 3 days. Reheat gently in the oven at 350°F (175°C) until warmed through, or in a skillet on the stovetop, covered, adding a splash of water to prevent drying.
