Ingredients You’ll Need
For the keto “mac”:
- 1 large head cauliflower, cut into small florets (or about 5 cups)
- 1 tbsp olive oil
- Salt & pepper
For the cheese sauce:
- 4 tbsp butter
- 3 cloves garlic, minced
- 3 tbsp cream cheese (full fat, please)
- 1 cup heavy cream
- 1 ½ cups shredded sharp cheddar cheese
- ½ cup shredded mozzarella cheese
- ½ cup grated Parmesan cheese
- 1 tsp Dijon mustard
- Salt & pepper to taste
The lobster star:
- 1 lb cooked lobster meat, roughly chopped (fresh or thawed frozen)
For the topping (optional but highly recommended):
- ¼ cup shredded cheddar
- ¼ cup crushed pork rinds (for that crispy, carb-free topping)
Step-by-Step Instructions
- Preheat your oven to 375°F (190°C). Grease a casserole dish—because nobody likes sticky situations.
- Roast the cauliflower: Toss cauliflower florets with olive oil, salt, and pepper. Spread on a baking sheet and roast for 15 minutes until just tender and starting to brown. This gives a nice bite and flavor boost.
- Make the cheese sauce: Melt butter in a saucepan over medium heat. Add garlic and cook until fragrant, about 1 minute.
- Add cream cheese and stir until melted and smooth. Slowly whisk in heavy cream, then add cheddar, mozzarella, and Parmesan cheese. Stir until melted and silky.
- Add Dijon mustard and season with salt and pepper. Give it a taste and adjust if needed — cheesy heaven alert.
- Combine lobster and cauliflower in a big bowl. Pour cheese sauce over and gently mix to coat everything like a cheesy lovefest.
- Transfer mixture to your casserole dish. Sprinkle the crushed pork rinds and extra cheddar on top for that epic crunch.
- Bake for 20–25 minutes until bubbly and golden on top.
- Let it cool for a few minutes before serving (hard to wait, but your tongue will thank you).
Common Mistakes to Avoid
- Skipping the cauliflower roast. Raw cauliflower in cheese sauce = mushy sadness.
- Using low-fat dairy. This is not the time to be skimpy with the cream or cheese.
- Not seasoning enough. Cheese can be salty, but cauliflower and lobster love a little extra love.
- Overmixing lobster. Treat it gently so it doesn’t turn rubbery.
- Skipping the crunchy topping. Trust me on this one.
Alternatives & Substitutions
- No lobster? Shrimp, crab, or even cooked chicken work great.
- No pork rinds? Use crushed almonds or almond flour mixed with butter for a crispy topping.
- Dairy-free? Use vegan cream cheese and dairy-free cheese shreds—but this might not be quite as gooey.
- No roasted cauliflower? Steamed cauliflower works but might be less flavorful and softer.
- Want it extra spicy? Toss in a pinch of cayenne or smoked paprika.
