Description
Golden roasted sweet potatoes, cauliflower florets, and red onion wedges baked in a rich, silky cream sauce with sun-dried tomatoes, garlic, Parmesan, and red pepper flakes until bubbling and deeply flavorful. A stunning, satisfying vegetarian dinner inspired by the viral Marry Me chicken that delivers every bit of the same bold, creamy comfort.
Ingredients
- 2 lbs (900g) sweet potatoes, peeled and cut into chunks
- 1 large cauliflower (680g), cut into florets
- 1 large red onion, cut into wedges
- 3 tablespoons (45ml) olive oil
- 1½ cups (350ml) heavy cream
- ½ cup (110g) sun-dried tomatoes, oil-packed and chopped
- 5 cloves garlic, minced
- ½ cup (50g) Parmesan cheese, grated
- ¼ cup fresh parsley, chopped
- ½ teaspoon red pepper flakes
- Salt and pepper to taste
Instructions
- Preheat oven to 425°F (220°C). Spread the sweet potato chunks, cauliflower florets, and red onion wedges across a large rimmed baking sheet. Drizzle with olive oil, season generously with salt and pepper, and toss to coat evenly.
- Roast for 25–28 minutes, turning once halfway through, until the vegetables are golden and caramelized at the edges with tender interiors.
- While the vegetables roast, combine the heavy cream, chopped sun-dried tomatoes, minced garlic, red pepper flakes, and half the Parmesan in a bowl. Stir well and season with salt and pepper.
- Transfer the roasted vegetables to a large baking dish. Pour the cream sauce evenly over the top.
- Sprinkle the remaining Parmesan over the surface.
- Return to the oven and bake at 400°F (200°C) for 18–20 minutes until the sauce is bubbling, the Parmesan is golden, and the cream has reduced slightly into a thick, silky coating around the vegetables.
- Remove from the oven, scatter fresh parsley over the top, and serve immediately.
Notes
- Do not crowd the vegetables on the baking sheet during the initial roast — overcrowding causes steaming rather than caramelizing and the golden edges are what add the most flavor to the finished bake.
- Oil-packed sun-dried tomatoes are essential here — they are softer, more flavorful, and integrate into the cream sauce far more beautifully than dry-packed varieties.
- Let the bake rest for 5 minutes after coming out of the oven — the cream sauce continues to thicken slightly as it settles and becomes even more luxurious.
