Roasted Mustard Cauliflower

Roasted Mustard Cauliflower is a flavorful and nutritious dish that makes a perfect side or main course for any meal. This recipe combines the earthy taste of cauliflower with the tangy kick of mustard and the warmth of aromatic spices, resulting in a dish that’s both comforting and satisfying. Let’s dive into the details of how to prepare this mouthwatering dish!

Ingredients Needed

For the cauliflower:

  • 1 head of cauliflower, cut into florets
  • 2 tablespoons olive oil
  • 2 tablespoons whole grain mustard
  • 2 cloves garlic, minced
  • 1 teaspoon smoked paprika
  • Salt and black pepper to taste

For the garnish (optional):

  • Fresh parsley, chopped
  • Lemon wedges

Preparation Steps

  1. Preheat the oven: Preheat your oven to 425°F (220°C) and line a baking sheet with parchment paper or aluminum foil for easy cleanup.
  2. Prepare the cauliflower: Wash the cauliflower head thoroughly and remove any green leaves. Cut the cauliflower into bite-sized florets, ensuring they are relatively uniform in size for even cooking.
  3. Make the mustard marinade: In a small bowl, combine the olive oil, whole grain mustard, minced garlic, smoked paprika, salt, and black pepper. Whisk the ingredients together until they form a smooth and well-combined marinade.
  4. Coat the cauliflower: Place the cauliflower florets in a large mixing bowl and pour the mustard marinade over them. Use a spatula or your hands to toss the cauliflower until each floret is evenly coated with the marinade.
  5. Roast in the oven: Spread the coated cauliflower florets in a single layer on the prepared baking sheet, ensuring they are not overcrowded. This allows them to roast evenly and develop a crispy exterior. Place the baking sheet in the preheated oven and roast for 20-25 minutes, or until the cauliflower is tender and golden brown, stirring halfway through to ensure even cooking.
  6. Garnish and serve: Once the cauliflower is roasted to perfection, remove it from the oven and transfer it to a serving platter. Garnish with freshly chopped parsley and lemon wedges for a burst of freshness and acidity. Serve the roasted mustard cauliflower hot as a delightful side dish or as a tasty addition to salads or grain bowls.

Variations and Substitutions

  • Spice it up: For an extra kick of heat, add a pinch of cayenne pepper or red pepper flakes to the mustard marinade.
  • Cheesy twist: Sprinkle grated Parmesan or nutritional yeast over the roasted cauliflower during the last few minutes of baking for a cheesy flavor boost.
  • Herb-infused: Experiment with different herbs and spices such as thyme, rosemary, or cumin to customize the flavor profile of the dish to your liking.

Health Benefits of Roasted Mustard Cauliflower

Roasted cauliflower is not only delicious but also packed with nutritional benefits. Cauliflower is low in calories but high in fiber, vitamins, and minerals, making it an excellent choice for promoting digestive health and overall well-being. Additionally, the mustard marinade adds antioxidant-rich ingredients like garlic and paprika, further enhancing the nutritional value of the dish.


1. Can I use other types of mustard for this recipe?

Absolutely! While whole grain mustard adds a delightful texture and flavor to the dish, you can use Dijon mustard or spicy brown mustard for a different twist. Feel free to experiment with different types of mustard to suit your taste preferences.

2. How do I store leftovers?

If you have any leftovers, store them in an airtight container in the refrigerator for up to 3-4 days. Reheat the roasted mustard cauliflower in the oven or microwave until warmed through before serving.

3. Can I use frozen cauliflower instead of fresh?

While fresh cauliflower is ideal for this recipe, you can certainly use frozen cauliflower florets if that’s what you have on hand. Just be sure to thaw and pat them dry before tossing them in the mustard marinade to ensure they roast evenly.

4. What can I serve with roasted mustard cauliflower?

Roasted mustard cauliflower pairs well with a variety of dishes, including grilled meats, roasted chicken, or even tofu for a vegetarian option. It also makes a delicious addition to salads, wraps, or sandwiches for a flavorful boost of veggies.
