What is Cauliflower Alfredo Sauce?
Cauliflower Alfredo sauce is made up of puréed cooked cauliflower, milk, and cheese. It has less fat and fewer calories than traditional Alfredo sauce, which includes butter, heavy cream, and Parmesan cheese. Those following a gluten-free, low-carb, or vegetarian diet should consider cauliflower Alfredo sauce, if you haven’t already. It’s most associated with pasta but we’re going to go in another direction with this recipe.
There’s this odd thing that happens when you put a little bit of roasted garlic, tender and golden brown onions, a dash of salt and pepper and a few healthy tablespoons of salty stock into a blender….then add cauliflower. It’s odd in the fact that you’re eating pureed vegetables are you’re TOTALLY okay with it. Like, on its own.

INGREDIENTS
- 1 small head garlic, chop it in half if it’s quite large
- 1/2 cup quinoa, uncooked
- 2 cups reduced-sodium vegetable broth, divided
- 3/4 tsp salt, divided
- 1 cup water
- 3 cups cauliflower, cut into bite-sized florets, 260 grams
- 1/2 tbsp olive oil
- 1/3 cup onion, roughly chopped
- 1/4 tsp crushed red pepper flakes
- black pepper
- 1/2 14.5-oz can quartered artichoke hearts, drained and roughly chopped, about 3/4 cup packed
- 1 1/2 cups roughly chopped spinach leaves, packed
- 1/2 cup grated Parmesan cheese, divided

INSTRUCTIONS
Prepare
Preheat your oven to 400°F. Chop the top of the head of garlic off so the tips of the cloves are exposed and rub a drizzle of olive oil into the head of garlic. Place two pieces of tinfoil on top of each other (shiny side inwards) and wrap the garlic up tightly. Place on a small pan and bake until the garlic is soft and roasted, about 35-40 minutes. Turn the oven down to 350°F. Spray an 8×8 inch pan with cooking spray and combine the quinoa, 1 cup of broth and 1/4 teaspoon of salt inside it, stirring well.
Bake
Cover with tinfoil and bake until the broth is absorbed, about 35-40 minutes.
Cook
While the quinoa cooks, combine the remaining broth and water in a large pot and bring to a boil. Once boiling, add in the chopped cauliflower, cover and boil until the cauliflower is fork-tender, about 6-7 minutes. While the cauliflower cooks, heat the olive oil in a medium pan over medium/high heat. Add in the onion and stir until golden brown, about 4-5 minutes. Using a slotted spoon, transfer the cauliflower into a large, high-powered blender. Add in the cooked onion, red pepper flakes, the remaining 1/2 teaspoon of salt and a few good pinches of pepper. Finally, add in 2 Tablespoon of the liquid that you cooked the cauliflower in and squeeze all of the roasted garlic into the blender.
Blend
Blend until smooth and pureed, scraping down the sides as necessary.
Stir
Once the quinoa is cooked, stir in all of the cauliflower Alfredo sauce, along with the chopped artichoke hearts, spinach leaves and 1/4 cup of the grated Parmesan cheese. Stir until well combined and the spinach begins to wilt. Cover and bake for another 15 minutes.
Finish and DEVOUR
Finally, sprinkle the remaining 1/4 cup of Parmesan cheese over the top of the casserole and bake, uncovered, until lightly golden brown, about 15-20 minutes. Let stand for 5-10 minutes (it’s hot) and DEVOUR!

How to store Quinoa Casserole
This casserole can last for up to four days in the fridge. You can also freeze it in a sealable freezer bag or wrap it in plastic wrap or aluminum foil. When it comes time to recommence eating, thaw it in the refrigerator and then reheat it in the oven or microwave. Be sure to let the casserole cool completely before storing it to prevent the growth of harmful bacteria.

Mary says
I’ve never cooked my own quinoa before. (Shocker, I know, where have I been?!) what is your favorite, or a suggestion of what kind to buy? I am totally getting some to make this recipe!! It looks so delicious!!
Taylor Kiser says
I actually always buy mine in bulk! But, Bob’s Red Mill is really good! For this recipe I would get just normal “quinoa” It should be a light yellowish color. There are different colored quinoas (red and black) and they have a more “Earthy” taste that I’m not a huge fan off! I hope that helps!! Quinoa is the best because it cooks in 15 mins…not like rice which takes half your life 🙂 Let me know what you try!
