Indulge in the savory comfort of a classic gratin without the carbs! This Keto Cabbage Au Gratin recipe transforms humble cabbage into an extraordinary, cheesy, and utterly satisfying low-carb side dish that will quickly become a family favorite. If you thought cabbage couldn’t be delicious, prepare to have your mind changed. This dish marries the delicate texture of perfectly cooked cabbage with a rich, creamy sauce and a golden, bubbly cheese topping, making it a perfect addition to any keto or low-carb meal plan.

Keto Cabbage Au Gratin: A Low-Carb Revolution
The term “au gratin” is a culinary classic, a French phrase literally meaning “by grating.” Traditionally, it refers to dishes topped with grated cheese or breadcrumbs (or both) and then baked or broiled until a golden, crispy crust forms. While potato gratins are undeniably popular, they’re packed with carbohydrates, making them unsuitable for a keto lifestyle. Our Keto Cabbage Au Gratin reimagines this beloved preparation method, replacing the carb-heavy potatoes with tender, nutrient-rich cabbage. The result is a dish that delivers all the creamy, cheesy decadence and crispy texture you expect from an au gratin, but with a significantly lower carb count, making it an ideal choice for anyone following a ketogenic diet.
This innovative take on a classic offers a comforting side dish that’s both flavorful and incredibly satisfying. We achieve that signature golden-brown, bubbly top by broiling the dish briefly at the end, ensuring a delightful contrast to the tender cabbage and luscious, melted cheese sauce underneath. It’s a testament to how creative cooking can adapt traditional favorites to fit modern dietary needs without sacrificing taste or texture. Prepare for a truly special dish that might just convert even the most skeptical cabbage eaters.

The Irresistible Blend: Cheese, Bacon, and Cabbage
What truly elevates this Keto Cabbage Au Gratin to gourmet status is the thoughtful combination of ingredients, each playing a crucial role in its rich flavor profile and satisfying texture. The addition of crispy bacon bits provides a delightful textural contrast and a savory depth that complements the mildness of the cabbage and the richness of the cheese. When preparing any keto meal that includes bacon, always remember to choose a sugar-free variety. Many cured bacons contain hidden sugars, which can quickly add unwanted carbohydrates to your diet. Checking the ingredient label ensures your dish remains perfectly keto-compliant.
Cabbage, the star of this keto side dish, is not only low in carbs but also incredibly versatile. For this particular recipe, green cabbage is highly recommended. Its slightly sweeter flavor becomes wonderfully tender when cooked, absorbing the creamy, cheesy sauce beautifully. While red cabbage can also be used, be aware that it tends to retain a bit more crunch and can sometimes impart a slightly stronger flavor. Experimentation is encouraged, but for a classic, tender au gratin experience, green cabbage is your best bet. The combination of succulent cabbage, savory bacon, and rich cheese creates a harmonious medley of flavors that will leave everyone asking for seconds.

Maximizing Flavor and Freshness: Tips for Preparation & Storage
One of the fantastic aspects of this cheesy cabbage recipe is how well it holds up as leftovers, making it an excellent candidate for your weekly meal prep. Preparing a larger batch allows you to enjoy this delicious low-carb side dish multiple times throughout the week, saving you time and effort on busy days. To ensure optimal freshness and taste, store any remaining Keto Cabbage Au Gratin in an airtight container in the refrigerator for up to three days. Beyond this period, while still safe to eat, the texture of the cabbage can become overly soft, diminishing the overall enjoyment of the dish. Proper storage ensures that each serving is as delicious as the first.
This versatile recipe isn’t just for side dishes; it can easily be transformed into a hearty main course. Imagine adding some shredded cooked chicken, savory ground beef, or even some leftover pulled pork directly into the cheesy sauce before baking. For a different presentation, instead of cutting the cabbage into wedges, you can shred it finely. Then, layer the shredded cabbage in a casserole dish with your chosen protein and the creamy, cheesy sauce. This simple modification creates a wholesome, one-dish meal that’s perfect for feeding your family with minimal fuss, making dinner both easy and incredibly satisfying while keeping it keto-friendly.

Perfect Pairings: What to Serve with Keto Cabbage Au Gratin
Cabbage, with its mild and subtly sweet flavor, is a remarkably versatile vegetable that pairs beautifully with a wide array of meats and main courses. This particular au gratin recipe, boasting earthy and savory notes from the onion, garlic, and Italian seasoning, makes it an exceptionally flexible accompaniment. Its creamy, cheesy profile provides a comforting contrast to many protein-focused dishes. Consider serving it alongside a rich and flavorful Keto Chicken Coq Au Vin, another French-inspired dish, where the delicate cabbage gratin can beautifully balance the robust wine-infused flavors of the chicken.
For those who enjoy pork, the cheesy cabbage also tastes absolutely delicious with a sweet and tender Keto Slow Cooker Pork Shoulder. The ease of a slow cooker meal combined with this baked side means a delicious, low-effort dinner is well within reach. Alternatively, the creamy textures and savory undertones of the cabbage au gratin make it a superb complement to a hearty Keto Salisbury Steak. The rich, mushroom-topped gravy of the Salisbury steak finds a perfect partner in the mild and creamy gratin, creating a well-rounded and deeply satisfying meal experience. This makes it an ideal choice for both everyday dinners and larger family gatherings, as one head of cabbage typically serves eight people, offering a budget-friendly yet impressive dish.

Pro Tips for a Perfect Keto Cabbage Au Gratin
Achieving the best possible Keto Cabbage Au Gratin involves a few key techniques that can elevate your dish from good to unforgettable. Firstly, don’t rush the roasting of the cabbage. Baking it initially helps tenderize it and draws out some of its natural moisture, concentrating its flavor. Ensure your baking dish is adequately greased to prevent sticking and promote even cooking. When sautéing the onions and garlic for the sauce, cook them until they are fragrant and translucent; this step builds a foundational layer of flavor for your creamy sauce.
For the cheese, while Gouda is recommended for its smooth melting properties and rich flavor, feel free to experiment with other keto-friendly cheeses like cheddar, Gruyere, Fontina, or even a blend of Parmesan and Mozzarella would work well. Just ensure they melt smoothly and have a flavor profile you enjoy with cabbage. The final broiling step is crucial for that iconic golden-brown, bubbly crust. Keep a close eye on it, as broilers can vary in intensity, and cheese can go from perfectly golden to burnt in a matter of seconds. A beautifully browned top adds a textural element that is essential to any au gratin. These small details ensure that every spoonful of your Keto Cabbage Au Gratin is bursting with flavor and boasts a delightful texture, making it a truly exceptional low-carb dish.

Keto Cabbage Au Gratin
Cheese truly makes everything better, and this Keto Cabbage Au Gratin will undoubtedly make you a cabbage enthusiast! It’s the ultimate low-carb side dish, offering rich flavor and comforting warmth.
Ingredients
- 1 head Cabbage, cut into wedges
- 2 tbsp Olive Oil
- 2 tbsp Butter
- 1/2 Onion, chopped
- 2 tsp Minced Garlic
- 1 tsp Italian Seasoning
- 1 tbsp Fresh Thyme
- 1 1/2 cups Heavy Whipping Cream
- 4 ounces Shredded Gouda Cheese
- Bacon Pieces, for garnish (ensure sugar-free)
- Parmesan Cheese, shredded, for garnish
- Salt and Pepper, to taste
Instructions
Preheat your oven to 350°F (175°C).

Drizzle the prepared cabbage wedges with olive oil and season generously with salt and pepper to taste. Arrange the seasoned cabbage in a well-greased 9×13 inch baking dish.
Bake the cabbage in the preheated oven for 40 minutes, or until it begins to tenderize.

While the cabbage is roasting, prepare the creamy sauce. In a skillet, melt the butter over medium heat. Add the chopped onions and sauté until they are soft and translucent, about 5-7 minutes.

Stir in the minced garlic and sauté for an additional 30 seconds until fragrant. Be careful not to burn the garlic.

Pour in the heavy whipping cream, Italian seasoning, fresh thyme, and season with salt and pepper to your preference. Bring the mixture to a gentle simmer.

Continue to simmer, stirring occasionally, until the sauce thickens to your desired consistency. This usually takes about 5-8 minutes. Remove the skillet from the heat and set the sauce aside.

Once the cabbage has roasted for 40 minutes, carefully pour the thickened creamy sauce evenly over the roasted cabbage in the baking dish. Return the dish to the oven and bake for another 30 minutes, allowing the flavors to meld.

Remove the dish from the oven. Evenly sprinkle the shredded Gouda cheese over the top of the cabbage and sauce. Place the dish under the broiler for 2-3 minutes, or until the cheese is melted, bubbly, and beautifully golden brown. Watch carefully to prevent burning.

Garnish your hot Keto Cabbage Au Gratin with crispy bacon pieces, a sprinkle of Parmesan cheese, and fresh chopped parsley if desired, just before serving. Enjoy!

Frequently Asked Questions (FAQ) About Keto Cabbage Au Gratin
- Can I make Keto Cabbage Au Gratin ahead of time?
- Yes, you can prepare the cabbage and sauce components separately a day in advance. Store them refrigerated in airtight containers. When ready to bake, combine, bake for the initial 40 minutes, then add cheese and broil as instructed. This can save significant time on the day of serving.
- What other cheeses can I use?
- While Gouda is fantastic, you can certainly experiment! Cheddar, Gruyere, Fontina, or even a blend of Parmesan and Mozzarella would work well. Choose cheeses that melt smoothly and have a flavor profile you enjoy with cabbage.
- Is this recipe freezer-friendly?
- It is generally not recommended to freeze cabbage au gratin. The texture of the cabbage can become very watery and mushy upon thawing and reheating, and the creamy sauce may separate. It’s best enjoyed fresh or refrigerated for up to 3 days.
- How can I make this dish vegetarian?
- To make it vegetarian, simply omit the bacon garnish. The dish is already rich and flavorful enough without it. You could also add a sprinkle of smoked paprika for a smoky flavor substitute, or roasted mushrooms for added umami.
- Why is my sauce not thickening?
- Ensure you’re simmering the heavy whipping cream gently and patiently. It takes a few minutes for the cream to reduce and thicken. If it’s still too thin, you can whisk in a tiny amount of xanthan gum (about 1/4 teaspoon per cup of liquid) to help it along, but usually, reduction is sufficient.
