Roasted Cauliflower with Lemon Vinaigrette

Roasted Cauliflower with Lemon Vinaigrette is delicious and only takes about 20 minutes to make.

Roasted Cauliflower with Lemon Vinaigrette sounds way fancier than it actually is. This simple recipe takes about 10 minutes to prep, 15 minutes to cook, and tastes like a dream. It’s so easy to be stuck in a vegetable side dish rut, but this recipe my friends, is here to save you from that.

Roasting is one of my all-time favorite ways to cook just about any vegetable, but cauliflower is the true roasted vegetable star in my book. It is so very good. I use roasted cauliflower as “noodles” when I want to enjoy a rich alfredo sauce or use it as “rice” to enjoy my favorite red curry, green curry, or butter chicken over. It’s such a delicious vehicle for rich sauces while saving calories.

Cauliflower simply roasted with little olive oil and salt is delicious, but by adding a simple bright lemon vinaigrette, you really make the roasted cauliflower a stand-alone side dish. This dish is easy enough to make for a quick weeknight meal but impressive enough that you could serve it at your next dinner party. No matter the reason, you have to try it. I know you are going to love it.

Tips and Tricks for making Roasted Cauliflower with Lemon Vinaigrette :

  • You can use traditional ground black pepper in the vinaigrette if you don’t have white.
  • You can add the zest of one lemon to the vinaigrette for a more lemony flavor. You won’t use all of it so store any leftovers in the fridge for up to 2 weeks, letting it come to room temperature before using. This dressing is excellent on spinach salads.
  • Short on time in the evening? Prep the vinaigrette ahead of time and cut up the cauliflower and stick it in a container in the fridge. Less prep means it’ll be on the table faster.

What are the best vegetables to roast in the oven?

My favorite veggies to roast are: potatoes, carrots, parsnips, sweet potatoes, broccoli, Brussels sprouts, zucchini, summer squash, onions, cauliflower and bell peppers. Roasting is a simple and hands off way to prepare vegetables and it makes them taste extra sweet. Have you had roasted beets? It’s my all-time favorite way to eat beets.

Looks amazing <3 Especially love those pretty onions 🙂

I don’t know why I’ve never roasted cauliflower! This recipe looks so good and easy. Going to have to try it.

I totally agree that roasted cauliflower may be the star of roasted veggies. This sounds delightful with the lemon vinaigrette to go with!

Looks delicious! I love anything lemony. I made the white bean crockpot soup you posted last week, and it was great too! 🙂

I absolutely love roasted cauliflower. It really is a show stopper! I could eat it all day, everyday!
