Ingredients
- 1 medium head cauliflower, cut into bite-sized florets
- 2 tbsp extra virgin olive oil
- 1 tbsp lemon juice
- 1 tsp Dijon mustard (verify GF)
- 0.5 tsp salt
- 0.25 tsp black pepper
- 0.5 tsp smoked paprika
- 0.25 tsp cayenne pepper (optional, for extra heat)
- 1 clove garlic, minced (optional)
Instructions
- 1
Preheat your oven to 400°F (200°C) and line a large baking sheet with parchment paper for easy cleanup. In a large bowl, toss the cauliflower florets with the extra virgin olive oil, ensuring each piece is lightly coated. This will help them roast evenly and develop a nice texture.

In a small bowl, whisk together the lemon juice, Dijon mustard, salt, black pepper, smoked paprika, and cayenne pepper (if using). Add the minced garlic to the dressing mixture, if desired, and stir to combine all the seasonings into a cohesive sauce.
- 3
Pour the prepared dressing over the olive oil-coated cauliflower florets in the large bowl. Toss everything together thoroughly for about 1-2 minutes, making sure every floret is well-coated with the spicy, aromatic mixture. This ensures maximum flavor infusion during roasting.

Spread the coated cauliflower in a single layer on the prepared baking sheet. Roast in the preheated oven for about 20-25 minutes, or until the cauliflower is tender when pierced with a fork and has developed golden-brown, slightly caramelized edges. You should notice a fragrant, slightly smoky aroma filling your kitchen.

Once roasted to perfection, carefully remove the baking sheet from the oven. Taste a floret and adjust seasoning with a pinch more salt or pepper if needed. Serve the spicy roasted cauliflower immediately as a delicious side dish.
