Polenta and Vegetables with Roasted Red Pepper Sauce

This Mediterranean-inspired polenta and vegetables dish is a vibrant celebration of texture and colour. By grilling the seasonal vegetables, including tender aubergines and sweet cherry tomatoes, you achieve a delicious charred depth that pairs perfectly with the creamy, golden polenta. This vegetarian main course is elevated by a zesty roasted red pepper sauce, which adds a bright, tangy finish to the savoury Parmesan crust.

Perfect for a nutritious midweek meal or a relaxed weekend lunch, this recipe is naturally gluten-free and packed with essential nutrients. If you have any leftover sauce, it keeps beautifully in the fridge and can be used to brighten up grilled halloumi or as a dip for crusty bread. Serve immediately while the cheese is bubbling for the ultimate comforting experience.

How to make Polenta and Vegetables with Roasted Red Pepper Sauce

Bring 725ml water to a boil in a medium-sized heavy saucepan. Add polenta in a stream, whisking to combine. Reduce heat to medium-low and simmer, stirring frequently, until thick, 3 to 5 minutes. Whisk in 50g Parmesan and season with cayenne and salt. Coat a 9-inch pie plate with cooking spray. Transfer polenta to pie plate, smooth into an even layer and let cool 15 minutes. Heat grill. Whisk garlic, thyme, lemon juice and oil in a bowl. Season with salt and pepper. Toss vegetables with dressing. Coat a baking sheet with cooking spray and arrange vegetables in 1 layer (or in 1 layer in a grill basket). Grill vegetables about 4 inches from heat until tender and slightly charred, 3 to 5 minutes on each side. Transfer to a platter. Combine all sauce ingredients in a blender or food processor and blend until smooth. Sprinkle polenta with remaining 50g Parmesan. Grill polenta in pie plate until golden brown, 2 to 3 minutes, then cut polenta into 8 triangles. Divide polenta among 4 plates. Top with vegetables, drizzle with sauce and sprinkle with chives. Serve any remaining sauce on the side.
