Fresh Cauliflower is Best

We’re always looking for different ways to cook and enjoy this beloved fresh vegetable. It’s got a great texture when cooked properly and it absorbs flavors in a great way too.  If you want to use frozen, you definitely can but fresh is so much better. Get yourself a head of fresh cauliflower, cut it in small bite sized pieces. Fresh cauliflower cooks with better texture and flavor than frozen. Even simple garlic and salt and pepper makes this fresh cauliflower a fantastic dish.

Can you make ahead?

This sriracha recipe is great to make ahead! Cooking it on the sheet pan allows you to cook a big batch all at once. In fact, you can even cook it on two sheet pans in the oven if you want. Just make sure to allow the cauliflower to cool completely before you freeze it. When you’re ready to eat, take it out of the freezer and re-heat in the microwave for a few minutes. We like to take it out of the fridge in the morning to allow it to thaw first before re-heating.
