Instructions:

1. Prepare the Cauliflower:
- Preheat your oven to 375°F (190°C).
- Remove the leaves and core from the cauliflower, and chop it into bite-sized florets.
- Toss the cauliflower florets in a large bowl with the vegetable oil to coat them evenly.
2. Roast the Cauliflower:
- Spread the cauliflower florets in a single layer on a baking sheet.
- Roast in the preheated oven for about 20-25 minutes until tender and slightly golden brown.
3. Make the Cheddar Sauce:
- While the cauliflower is roasting, heat a medium-sized saucepan over medium heat.
- Pour in the heavy whipping cream and bring it to a gentle simmer, stirring occasionally.
- Add the cream cheese to the saucepan, stirring until it’s completely melted and the mixture is smooth.
- Stir in the mustard, black pepper, and garlic powder.
4. Add the Cheddar Cheese:
- Gradually add the shredded cheddar cheese to the saucepan, a little at a time, stirring constantly until the cheese is melted and the sauce is smooth and creamy. Be careful not to overheat, as the cheese can become grainy if overheated.
5. Combine Cauliflower and Cheese Sauce:
- Once the cauliflower is roasted, transfer it to a large mixing bowl.
- Pour the cheddar cheese sauce over the roasted cauliflower, stirring gently to combine until all the florets are thoroughly coated in the sauce.
6. Serve:
- Transfer the cauliflower mac & cheese to a serving dish.
- Optionally, you can return it to the oven for an additional 5-10 minutes to get a slightly crispy top.
7. Enjoy:
- Serve immediately and enjoy this creamy, cheesy keto-friendly dish!

Keto cauliflower mac & cheese with creamy cheddar sauce FAQ:

How long do I roast the cauliflower?

Roast the cauliflower florets in a preheated oven at 375°F (190°C) for about 20-25 minutes until they are tender and slightly golden brown.

What is the best way to store leftovers?

Store any leftovers in an airtight container in the refrigerator for up to 3 days. Reheat in the microwave or oven until warmed through.

Can I substitute the cheddar cheese?

Yes, you can substitute the cheddar cheese with other keto-friendly cheeses like mozzarella or gouda, but it may alter the flavor and texture of the sauce.

How do I know when the mac & cheese is done?

The dish is done when the cauliflower is tender and the cheese sauce is smooth and creamy, ideally served right after combining. If you choose to bake it further, an additional 5-10 minutes should create a slightly crispy top.

What can I use instead of cream cheese?

If you're looking for a substitution, you can try mascarpone cheese or Greek yogurt, though these options may change the flavor and consistency slightly.

Tips:

- Choose a fresh, firm cauliflower for the best texture. Frozen cauliflower can be used but be sure to drain it well to avoid a watery dish.

- For a richer flavor, grate your own cheddar cheese rather than using pre-shredded cheese.

- Feel free to add extra seasonings such as paprika or a mix of herbs to give the sauce a personal touch.

- If you like a crispier texture, consider baking the dish in the oven for a few minutes after mixing the sauce with the cauliflower.
