Step‑by‑Step Instructions for Keto Sausage Cabbage Casserole
Step 1: Preheat the Oven
Begin by preheating your oven to 400°F (200°C). This initial step ensures that the Keto Sausage Cabbage Casserole cooks evenly and achieves a lovely golden-brown finish. While the oven heats up, gather your equipment: a large knife, cutting board, and a 9×13 baking dish for assembling the casserole.
Step 2: Prepare the Cabbage
Slice the cabbage into thin strips, discarding any tough stem pieces. Aim for about ½-inch thick pieces so they roast beautifully. Once sliced, place the cabbage in your prepared baking dish, ensuring it covers the bottom evenly. The cabbage will act as a wholesome base for your casserole, providing that satisfying low-carb twist.
Step 3: Add Aromatics
Next, thinly slice the onion and finely mince the garlic. Add these aromatics to the cabbage in the baking dish and give everything a gentle toss to combine. Their natural sweetness will infuse the Keto Sausage Cabbage Casserole, enhancing the overall flavor as it bakes in the oven.
Step 4: Incorporate Butter and Cream Cheese
Distribute small pats of butter and cubes of cream cheese evenly over the vegetable mixture. The butter will melt and create a rich flavor base, while the cream cheese will contribute to the creamy Alfredo sauce. Ensure every piece is touched by that deliciousness; it will make all the difference in taste!
Step 5: Add Cream and Seasonings
Spoon dollops of sour cream over the mixture, followed by pouring heavy whipping cream into the dish. Generously season with salt, pepper, and garlic powder to enhance the flavors. Stir everything lightly, ensuring an even coating of the creamy base, preparing for a delightful bake.
Step 6: Bake the Casserole
Cover the baking dish with aluminum foil and place it in the preheated oven. Bake for 35-40 minutes, or until the cabbage begins to soften and caramelize slightly. You should see a nice golden hue forming as the flavors meld together, creating a comforting aroma that’s hard to resist.
Step 7: Cook the Sausage
While your casserole bakes, heat a skillet over medium heat and add some melted butter. Cook your choice of sausage, breaking it into pieces as it browns, for about 15-20 minutes. Stir occasionally until the sausage is cooked through and has a delicious, golden exterior, then set it aside for the final assembly.
Step 8: Add Lemon and Parmesan
Once the cabbage is baked, carefully remove the dish from the oven. Drizzle fresh lemon juice over the roasted mixture, then sprinkle with parmesan cheese for that cheesy goodness. Give everything a gentle stir to combine, ensuring the rich flavors are evenly distributed throughout the Keto Sausage Cabbage Casserole.
Step 9: Combine with Sausage
Fold the cooked sausage pieces into the casserole mixture, gently stirring to incorporate them. This step not only adds heartiness but also a savory flavor that elevates the whole dish. Make sure to evenly distribute the sausage throughout so every bite is packed with flavor.
Step 10: Final Bake for Cheesy Finish
Return the casserole to the oven uncovered and bake for another 10 minutes, or until the cheese is melted and bubbly. The top will be beautifully golden, hinting at the creamy, cheesy filling underneath. This final bake creates a delightful crust that will have everyone at the table eager to dig in!
Step 11: Garnish and Serve
After baking, take the casserole out of the oven and let it cool for a few minutes. Finely chop fresh parsley and sprinkle it all over as a colorful garnish. This Keto Sausage Cabbage Casserole is now ready to serve—just scoop into bowls and enjoy the comforting, creamy delight of this low-carb dish!

Make Ahead Options
These Keto Sausage Cabbage Casserole preparations make weeknight dinners a breeze! You can chop the cabbage, onion, and garlic up to 24 hours in advance and store them in an airtight container in the refrigerator to keep them fresh. You can also pre-cook the sausage and store it separately for an even faster assembly. When you’re ready to enjoy this delicious casserole, simply layer the prepped ingredients in your baking dish, add the cream and cheeses, and bake as directed. This way, your casserole is just as comforting and creamy but saves you precious time on busy evenings!
