3 cloves garlic, minced – Aromatic depth.

1 teaspoon dried thyme – Earthy herbal flavor.
1 teaspoon dried parsley – Mild freshness.

2 cups shredded cheddar cheese (divided) – Melts into creamy interior.
1 cup grated Parmesan cheese – Creates golden crust and savory depth.

Step-by-Step Instructions

Preheat the Oven

Preheat oven to 375°F (190°C). Lightly grease a casserole dish.

Prepare the Cauliflower

Bring a large pot of salted water to a boil. Add cauliflower florets and cook for 5–7 minutes until just fork-tender. Drain thoroughly to prevent excess moisture.

Sauté the Garlic

In a large skillet, melt butter over medium heat. Add minced garlic and cook for about 1 minute until fragrant.

Make the Cream Sauce

Pour heavy cream into the skillet. Bring to a gentle simmer. Stir in onion powder, thyme, parsley, salt, and pepper. Simmer 2–3 minutes until slightly thickened.

Combine Ingredients

In a large mixing bowl, combine cooked cauliflower, diced ham, and 1 cup of shredded cheddar. Pour cream sauce over mixture and gently stir until evenly coated.

Assemble the Casserole

Transfer mixture to prepared casserole dish. Top with remaining cheddar and all of the Parmesan cheese.

Bake

Bake for 25–30 minutes until cheese is melted, golden, and bubbling around the edges.

Rest and Serve

Let casserole rest for 5 minutes before serving to allow it to set.

Recipe Notes & Tips

Drain Cauliflower Well – Excess water can thin the sauce.
Use Freshly Grated Cheese – Melts smoother and avoids grainy texture.
Avoid Overcooking Cauliflower – Keeps casserole from becoming mushy.
Add Extra Protein – Stir in cooked bacon for added richness.
Season Carefully – Ham can be salty; taste before adding extra salt.
Broil for Extra Crisp Top – 1–2 minutes at the end if desired.

Why This Recipe Works

Ham contributes savory depth and protein, balancing the richness of the cream and cheese. At just 350 calories per serving and low in carbohydrates, it delivers comfort without compromising keto goals.
