Ingredients
Equipment
Method
- Soften the Cabbage. You'll need: 2 pounds green cabbage, 2 tbsp butter, 1 cup water (divided as needed), 1 tsp table salt, ¼ tsp black pepper, and ½ tsp red pepper flakes. Melt the butter in a large, deep skillet over medium-high heat. Add the chopped cabbage, salt, black pepper, and red pepper flakes, tossing to coat. Pour in ½ cup water, cover, and cook for approximately 10 minutes, stirring occasionally, until the cabbage is tender with a slight bite. Add up to another ½ cup water if needed to prevent drying. Uncover and allow any excess water to evaporate.
- Make the Creamy Cheese Sauce. You'll need: ½ cup heavy cream, ½ cup shredded Asiago cheese, and ¼ cup shredded Parmesan cheese.Reduce the heat to medium-low. Stir the heavy cream into the cabbage, then add the cheeses. Stir until melted and the cabbage is evenly coated. No thickener is needed.
- Assemble the Gratin. You'll need: ½ cup shredded Asiago cheese and ¼ cup shredded Parmesan cheese.Taste the cabbage mixture and adjust the seasoning if needed. Transfer to a lightly greased baking dish and spread evenly. Sprinkle the remaining cheeses over the top.
- Bake Until Golden. Preheat the oven to 375°F. Bake for 15–18 minutes, until the cheese is melted and bubbling. For a more golden-brown topping, optionally broil for 2–3 minutes, watching closely to prevent burning. Let rest for 5 minutes before serving.

Let us know how it was!Tips for the Best Keto Cabbage Gratin
Prevent a watery gratin. Let excess moisture evaporate from the cabbage before adding the heavy cream to keep the sauce rich and creamy.
Use freshly shredded cheese. Pre-shredded cheeses may contain anti-caking agents that affect melting. Freshly shredded Asiago and Parmesan create a smoother, creamier sauce.
What to Serve with Keto Cabbage Gratin
This creamy cabbage gratin makes a rich, cheesy side dish that pairs well with simply seasoned proteins. Try serving it alongside:
- Roasted chicken or pork chops
- Grilled steak
- Baked ham
- Pan-seared chicken breasts
Because the gratin is already rich and creamy, it pairs especially well with meats that don’t have heavy sauces.
Frequently Asked Questions
Can I substitute Parmesan for Asiago?
Yes. You can replace the Asiago with an equal amount of freshly shredded Parmesan. The flavor will be sharper and saltier, and the texture may be slightly less creamy.
How can I thicken the sauce if it’s too thin?
The heavy cream and melted cheeses should create a creamy coating without additional thickeners. If the sauce seems too thin, simmer gently uncovered for a few minutes to reduce excess moisture. If needed, a very small amount of xanthan gum may help, but add it gradually while stirring to avoid clumps or a gummy texture.
