Preheat oven: Set your oven to 400°F (200°C). This ensures your cauliflower will roast perfectly, developing that inviting golden-brown color.

-
Arrange on baking sheet: Spread the coated cauliflower in a single layer on a parchment-lined baking sheet. This allows for even roasting and helps achieve that nice, crispy texture.
-
Roast the cauliflower: Pop the baking sheet into the preheated oven and let it roast for 30 minutes, or until the cauliflower is tender and lightly browned. The smell that fills your kitchen during this time is simply divine!

Dijon Mustard Roasted Cauliflower Recipe FAQs
How do I choose ripe cauliflower?
Absolutely! When selecting cauliflower, look for firm heads with tightly packed florets. Avoid any specimens that are discolored or have dark spots all over, as these are signs of overripeness. A fresh cauliflower should also feel heavy for its size, which indicates it’s full of moisture!
How should I store Dijon Mustard Roasted Cauliflower?
To keep your leftover Dijon Mustard Roasted Cauliflower fresh, store it in an airtight container in the fridge for up to 3 days. Be sure to let it cool completely before sealing the container. This helps to prevent moisture buildup that can lead to sogginess!
Can I freeze Dijon Mustard Roasted Cauliflower?
Yes! To freeze, spread the cauliflower in a single layer on a baking sheet and place it in the freezer until solid. Once frozen, transfer the cauliflower to a freezer-safe bag, where it will keep for up to 3 months. When you’re ready to eat, just reheat in the oven at 350°F (175°C) until heated through, about 10-15 minutes.
What if my cauliflower isn’t browning while roasting?
If your cauliflower isn’t browning, it might be overcrowded on the baking sheet or your oven temperature could be slightly low. Make sure the florets are spaced out in a single layer and, if necessary, bump up the temperature by 25°F (about 15°C). For added browning, finishing with a brief broil can also work wonders!
Is this recipe suitable for people with dietary restrictions?
Yes, the Dijon Mustard Roasted Cauliflower recipe is naturally vegetarian and gluten-free! However, check your mustard brand to ensure it doesn’t contain any allergens if someone in your household has specific dietary restrictions. Always a good idea to read those labels!
Can pets eat cauliflower?
While dogs can safely enjoy cooked cauliflower in small quantities, it’s best to avoid giving them any added seasonings or oils. Remember, moderation is key! Always consult your veterinarian before introducing new foods into your pet’s diet.
