Tomato-Basil Sauce with Polenta

This vibrant tomato and basil sauce with polenta turns simple store-cupboard ingredients into a sophisticated vegan meal. By roasting cherry tomatoes in a sealed parchment parcel, the juices concentrate and mingle with garlic and shallots to create a rich, fragrant sauce that perfectly complements the golden polenta. The contrast between the slightly crisp exterior of the polenta rounds and the jammy, herb-infused tomatoes makes for a truly satisfying plant-based dinner.

As a naturally gluten-free and vegan dish, this recipe is an excellent choice for a healthy midweek supper or a fuss-free weekend lunch. The method of parcel-cooking, or 'en papillote', ensures the flavours remain intense while keeping prep and clean-up to a minimum. Serve these rounds as a light main course alongside a crisp green salad for a balanced and colourful Mediterranean-inspired feast.

Ingredients for Tomato-Basil Sauce with Polenta

  • 80ml extra-virgin olive oil, divided

  • 1 16- to 500g packaged cooked polenta log, cut into 1/2-inch rounds

  • 900g cherry tomatoes (about 900g )

  • 7 garlic cloves, thinly sliced

  • 1 shallot, finely chopped (about 40g )

  • 2 teaspoons kosher salt

  • 1/2 teaspoons freshly ground black pepper

  • 8 large sprigs basil

How to make Tomato-Basil Sauce with Polenta

Arrange racks in upper and lower thirds of oven; preheat to 425°. Line a large rimmed baking sheet with foil and brush with 1 tablespoon oil. Arrange polenta rounds on oiled sheet.

Very coarsely chop (do not purée) half the tomatoes in a food processor. Cut remaining tomatoes in half (quarter if large). Combine tomatoes in a bowl with 60ml oil and remaining ingredients. Toss to coat.

Stack three 24x12" sheets of parchment paper on another baking sheet. (Don't use foil-the tomato acid will react with aluminum.) Spoon tomato mixture onto one side of stacked parchment. Fold parchment layers over mixture and crimp edges tightly to form a sealed packet.

Place baking sheet with tomato packet on upper rack and sheet with polenta on lower rack. Bake, turning polenta rounds once, until polenta is light golden and tomatoes are saucy (carefully open packet to check; steam will escape), 25-30 minutes. (You can also cook polenta in a grill pan or on a charcoal or gas grill.)

Spoon tomato sauce over polenta.
