🧾 Ingredients
✅ Classic Keto Alfredo Sauce
- 4 tbsp unsalted butter
- 3 cloves garlic, minced
- 1 cup heavy whipping cream
- ¾ cup freshly grated Parmesan cheese
- ¼ tsp black pepper
- Salt to taste
Optional Flavor Boosts
- Pinch of nutmeg (traditional Italian touch)
- 2 tbsp cream cheese for extra thickness
- 1 tbsp chopped fresh parsley for garnish
- ¼ tsp red pepper flakes for a spicy kick
🧿 Ingredient Notes
- Butter: Provides the rich, silky base for the sauce. Unsalted is best so you control the flavor.
- Heavy Cream: Keeps the sauce thick, luxurious, and keto-approved. Avoid milk — it adds unnecessary carbs.
- Parmesan Cheese: Freshly grated melts smoother than pre-shredded (which contains anti-caking agents).
- Garlic: Gives depth and restaurant-style flavor. Fresh minced garlic works best.
- Cream Cheese: Optional but great if you like a thicker, extra-creamy Alfredo.
👩🍳 Step-by-Step Instructions
Step 1: Melt the Butter
Place a medium saucepan over low to medium heat. Add the butter and let it melt slowly until it becomes glossy and aromatic — avoid browning it.
Step 2: Add Garlic
Stir in the minced garlic and sauté for about 30–60 seconds until fragrant. The kitchen will instantly smell amazing! Do not let the garlic brown, or it may turn bitter.
Step 3: Pour in the Cream
Slowly add the heavy cream, stirring gently as it blends with the melted butter. Let it simmer for 3–4 minutes, stirring occasionally. The sauce will start to thicken into a creamy, luscious texture.
Step 4: Add Parmesan Cheese
Reduce the heat to low and gradually whisk in the Parmesan cheese until it melts completely. The sauce should become smooth, velvety, and rich.
Step 5: Season & Serve
Add black pepper and salt to taste. If desired, stir in a pinch of nutmeg or red pepper flakes. Remove from heat and serve warm over your favorite low-carb base.
Pro Tip: The sauce thickens as it cools. If it becomes too thick, whisk in 1–2 tbsp more cream to adjust consistency.
💡 Pro Tips & Variations
- Add Cream Cheese: For an extra thick, restaurant-style sauce, add 2 tablespoons of cream cheese when you add the heavy cream.
- Make it Herb-Infused: Add fresh basil, parsley, or Italian seasoning for an herby twist.
- Protein Boost: Toss with grilled chicken, shrimp, or salmon for a full keto meal.
- Veggie Version: Mix with sautéed spinach, roasted broccoli, or zucchini noodles for a low-carb Alfredo bowl.
- Storage Tip: Store in a glass jar — sauce continues to thicken and stays fresh longer.
