Cauliflower Keto Casserole Recipe

Cauliflower: The star of the dish, providing a low-carb base with a mild flavor.

Cheddar cheese: Adds a rich, creamy texture and sharp flavor to the casserole.

Sour cream: Contributes to the creaminess and tanginess of the dish.

Green onions: Adds a fresh, slightly pungent flavor that complements the other ingredients.

Garlic powder: Enhances the overall flavor with a hint of garlic.

Salt: Essential for seasoning and bringing out the flavors of the other ingredients.

Black pepper: Adds a touch of heat and depth to the dish.

To ensure your cauliflower is perfectly tender and not mushy, after boiling, immediately transfer the florets to an ice bath. This will stop the cooking process and help maintain a firm texture. Additionally, make sure to drain the cauliflower thoroughly to avoid excess water in your casserole, which can affect the consistency of the dish.

• Cauliflower - Substitute with broccoli: Broccoli has a similar texture and can be used in place of cauliflower for a different flavor profile while still being keto-friendly.

• Shredded cheddar cheese - Substitute with shredded mozzarella cheese: Mozzarella melts well and provides a mild flavor that complements the other ingredients.

• Sour cream - Substitute with Greek yogurt: Greek yogurt has a similar creamy texture and tangy flavor, making it a good low-carb alternative.

• Chopped green onions - Substitute with chopped chives: Chives offer a similar mild onion flavor and can be used as a garnish or mixed into the casserole.

• Garlic powder - Substitute with onion powder: Onion powder provides a different but complementary flavor that can enhance the overall taste of the dish.

• Salt - Substitute with soy sauce: Soy sauce adds a savory umami flavor and can be used in moderation to replace salt.

• Black pepper - Substitute with white pepper: White pepper has a slightly different heat profile and can be used to add a subtle spiciness without altering the color of the dish.

• Allow the cauliflower casserole to cool completely before storing. This helps prevent condensation, which can make the dish soggy.
• Transfer the cooled casserole to an airtight container. If you prefer, you can also use a resealable plastic bag, but make sure to remove as much air as possible.
• Store the container in the refrigerator. The cauliflower casserole will keep well for up to 3-4 days.
• For longer storage, consider freezing the casserole. Wrap the entire baking dish tightly with plastic wrap, followed by a layer of aluminum foil. Alternatively, you can portion the casserole into individual servings and place them in freezer-safe containers or bags.
• Label the containers with the date to keep track of freshness. The cauliflower casserole can be frozen for up to 2-3 months.
• When ready to reheat, if the casserole is frozen, thaw it in the refrigerator overnight. This ensures even reheating and maintains the texture.
• Preheat your oven to 350°F (175°C). Remove any plastic wrap and cover the casserole with aluminum foil to prevent it from drying out.
• Bake the thawed casserole for about 20-25 minutes, or until heated through. If reheating from the refrigerator, it may take slightly less time.
• For a crispier top, remove the foil during the last 5-10 minutes of reheating. This will help the cheddar cheese become bubbly and golden again.
• Enjoy your reheated cauliflower keto casserole as if it were freshly made!
