Why substitute cauliflower for macaroni?

I absolutely love mac and cheese! It’s one of my favorite dishes, and you can be so creative with it! I love to experiment with different cheeses and flavors. Sometimes I may add seafood in it, bacon, or truffles for extra flavor. What’s unique about this recipe? It does not contain all the carbs due to the cauliflower substitution, is keto-friendly, but still gives you that amazing mac and cheese taste!

Ketogenic-friendly recipes are generally low in carbohydrates and higher in fats. Following a ketogenic diet helps you to burn fats more easily and is beneficial for weight loss. When you reduce your carb intake, your body enters a state called “ketosis” where your body burns fat for energy.

Ingredients

Cauliflower Heads: Not one, but two whole heads! Make sure they’re washed and stripped down to their florets. This veg is about to become something un-veggie-lievably tasty!
Salt, Black Pepper, & Garlic Powder: The classic trio for taste! Season to your heart’s desire because flavor town, here we come!
Mascarpone Cheese: Oh, the creaminess, folks! This Italian wonder cheese takes our sauce to creamy dreamy levels.
Large Eggs: Binding agents in the house! They keep everything nice and tight. No crumbles on our watch.
Heavy Whipping Cream: Say hello to velvety richness! It’s the secret weapon for that ultra-luxurious texture.
Shredded Cheeses: Triple threat alert! We’ve got creamy Havarti, smooth Colby Jack, and classic Mild Cheddar. This cheesy trinity is the soul of your dish.
Fresh Chopped Parsley: A sprinkle for color, a dash for fresh herby kicks! It’s the garnish that seals the deal with a kiss of green.

How to make Cauliflower Mac and Cheese

Set the Stage: Crank up your oven to 350 degrees because things are about to get heated!
Steam Dream: Grab a pot, pour in about 2 inches of water, pop in a steamer basket, and get that H2O simmering. Toss in your cauliflower heads, cover, and let ’em steam for around 10 minutes – you’re looking for fork-tender vibes.
Chop and Rock: Once those cauliflowers are nice and soft, chop ’em up into cute 1-inch chunks. Plant these little treasures in a baking dish, at least 9 inches – space is key!
Season Like a Boss: Sprinkle that cauliflower with salt, pepper, and garlic powder. How much? Your taste buds are the limit.
Custard’s Last Stand: In a bowl, play mix-master with the mascarpone cheese, eggs, and heavy cream until it’s smooth like a custard playlist.
Mix and Mingle: Pour that creamy dream over your cauliflower, ensuring an even coat. Dive in with 2 cups of shredded cheeses, and mix it up.
Cheese, Please!: Spread the last cup of shredded goodness on top. Hit it with a bit more pepper, because why not?
Bake and Shake: Slide your dish into the oven and bake for 35 minutes, or until you’ve got that bubbly action going. Want a golden glow? Broil it for an extra 1-2 minutes.
Garnish and Relish: Fancy it up with a sprinkle of fresh parsley.

What type of cheeses should I use ?

My number one tip when making any mac and cheese is to use block cheese. Block cheeses are free from chemicals typically found in shredded cheeses. Shredded cheeses contain unhealthy additives used to prevent caking. You can easily grate block cheeses, and they add a creamier taste to your dish!

When I make mac and cheese, I love to try different cheeses. Some of my favorite cheeses to use are creamy havarti, gouda, gruyere, white cheddar, and mild and sharp cheddar. Mascarpone (Italian cream cheese) is also one of my favorite cheeses to use in mac and cheese.

How do I steam the cauliflower heads?

There are multiple ways to steam cauliflower heads. The goal is to soften the cauliflower prior to baking it. Keep in mind, unlike macaroni pasta, cauliflower produces a lot of its own moisture.

The first way is to use a large pot with a steamer basket over medium-high heat. With this method, add a couple of inches of water in the bottom of the pan, place the steamer basket on top of the pot and place the cauliflower in the basket. Afterwards, cover the pot with a lid. Steam the cauliflower heads for approximately 10 minutes.

If you do not have a steamer, another method is to place a metal colander over a large pot filled with two inches of water. With this method, you have to make sure the pot is large enough to hold the colander. Place a lid over the colander to make sure the cauliflower softens completely.
A third method is to simply fill a large pot with a couple of inches of water and place the cauliflower heads inside. Place the lid on top of the pot, steam for 10 minutes, and make sure to drain the excess water off the cauliflower once removed.

Lastly, you can use the microwave to steam your cauliflower! Fill the bottom of a microwave-safe bowl with water, and place the cauliflower heads inside the bowl. Cover the bowl with a lid, leaving a small corner open to vent, and microwave on high for 5 minutes or until the cauliflower is softened.

Storage and Reheating

Had your fill but still have leftovers of that delish Cauliflower Mac and Cheese? No problemo! Here’s the lowdown on how to store this creamy concoction so you can relive the yumminess all over again.

Cool It, Baby: First thing’s first, don’t jump the gun! Let your Cauli-Mac masterpiece cool down to room temperature after its hot date with your oven. Hot food in the fridge is a no-no — it brings up the temp and messes with the chill vibe (and safety!).

Airtight is Alright: Once it’s cool, spoon any leftovers into an airtight container — we’re keeping air and moisture at bay, folks. This step keeps your Cauli-Mac fresh and wards off those pesky fridge flavors.

Fridge Fun: Pop your airtight wonder into the refrigerator. It’ll stay tasty for 3 to 5 days, giving you plenty of time to enjoy those cheesy, creamy leftovers.

Freeze for Ease: Want to save some for a rainy day? You can totally freeze it! Just make sure it’s in a freezer-safe container (airtight again, pals). It’ll keep for about 2-3 months. Thaw it in the fridge overnight when you’re ready for round two.

Reheat and Eat: When you’re ready to dive back in, you can reheat it in the oven or microwave. If you’re going the oven route, 350 degrees for 20 minutes should do the trick — just until it’s heated through. Microwave folks, start with a 2-minute zap and add more time if needed.

Pro Tip: Add a splash of milk or cream during reheating to keep it creamy and dreamy, preventing it from drying out.

Remember, food safety is key, so if you’re ever in doubt, it’s safer to toss it out.
