Ingredients for Keto Whole Roasted Cauliflower with Butter Sauce
To make this dish keto-friendly, we focus on whole, fresh cauliflower and rich, healthy fats to create a flavorful, satisfying recipe. Each ingredient serves to enhance the natural flavor of cauliflower while keeping the dish low in carbohydrates. Let’s take a look at the key ingredients:
Here’s what you’ll need:
- 1 Medium Head of Cauliflower
- Choose a fresh cauliflower head that is firm with tight florets. It should be free of brown spots, which indicate spoilage. Cauliflower is an excellent choice for a keto diet as it’s low in carbs and provides fiber, vitamins, and antioxidants.
- 3 tablespoons Olive Oil (For Roasting)
- Olive oil is a healthy fat that helps the cauliflower roast to perfection, providing a crispy, golden exterior. It also contributes to the flavor of the dish, enhancing the earthy notes of cauliflower.
- Salt and Pepper (To Taste)
- Salt is essential for bringing out the natural flavors in the cauliflower. Freshly ground black pepper adds a subtle heat, but you can adjust the amount to suit your taste preferences.
- 1/2 teaspoon Garlic Powder
- Garlic powder adds a savory depth to the roasted cauliflower, infusing it with rich, aromatic flavors that complement the butter sauce.
- 1/4 teaspoon Paprika
- Paprika not only enhances the color of the cauliflower but also gives a subtle smoky flavor that balances the richness of the butter sauce.
- 2 tablespoons Butter (For Butter Sauce)
- Butter is the key to creating a creamy, rich sauce that adds a velvety texture to the cauliflower. It also helps with flavor enhancement and complements the roasted cauliflower’s natural sweetness.
- 1 tablespoon Fresh Lemon Juice
- Fresh lemon juice adds a touch of acidity that helps to cut through the richness of the butter sauce, providing a refreshing contrast to the dish’s flavors.
- 1 tablespoon Fresh Parsley (Finely Chopped)
- Fresh parsley adds a pop of color and a hint of freshness to the dish. It also enhances the overall flavor with its mild, slightly peppery taste.
- 1 tablespoon Grated Parmesan Cheese (Optional)
- Parmesan cheese adds a savory, umami kick to the cauliflower and butter sauce. This optional ingredient is a great addition for those looking to add extra flavor and a slightly cheesy twist to the dish.
Instructions for Preparing Keto Whole Roasted Cauliflower with Butter Sauce
Now that we have all the ingredients, let’s dive into the process of creating this stunning keto whole roasted cauliflower dish. Follow these steps carefully to achieve the perfect roasted cauliflower, bathed in a delicious, buttery sauce.
Step 1: Preheat the Oven
Start by preheating your oven to 400°F (200°C). This high heat will ensure that the cauliflower roasts evenly and achieves a golden-brown, crispy exterior while staying tender on the inside.
Step 2: Prepare the Cauliflower
Remove the leaves from the cauliflower head and trim the stem so that it can stand upright. If necessary, use a sharp knife to remove any excess green parts and trim the base so that the cauliflower sits evenly on the baking sheet.
Step 3: Season the Cauliflower
Place the cauliflower head on a baking sheet lined with parchment paper or a silicone baking mat. Drizzle the cauliflower with olive oil and use a brush or your hands to coat it evenly. Sprinkle the cauliflower with salt, pepper, garlic powder, and paprika, making sure to season it thoroughly on all sides.
Step 4: Roast the Cauliflower
Roast the cauliflower in the preheated oven for 35-45 minutes, depending on the size of your cauliflower. After 25 minutes, check the cauliflower and use a spoon to baste it with the olive oil on the baking sheet to help it brown evenly. Continue roasting until the cauliflower is golden brown and tender when pierced with a fork. Keep an eye on it to ensure it doesn’t overcook or burn.
Step 5: Prepare the Butter Sauce
While the cauliflower is roasting, prepare the butter sauce. In a small saucepan, melt the butter over medium heat. Once melted, remove the saucepan from the heat and stir in the fresh lemon juice, finely chopped parsley, and grated Parmesan cheese (if using). Mix everything well, ensuring the sauce is smooth and well combined.
Step 6: Baste the Cauliflower with Butter Sauce
Once the cauliflower is done roasting, remove it from the oven and let it cool for a few minutes. Using a spoon or baster, pour the butter sauce over the cauliflower, making sure to coat it evenly. Allow the sauce to soak into the cauliflower, enhancing its flavor and adding richness.
Step 7: Garnish and Serve
Sprinkle any remaining fresh parsley over the cauliflower for a pop of color and freshness. If you like, add a bit more grated Parmesan cheese on top. Slice the cauliflower into wedges and serve immediately. This dish pairs beautifully with your favorite keto main course, such as roasted chicken, steak, or a keto-friendly salad.
