For the Keto Alfredo Sauce
- 4 tbsp unsalted butter
- 2 cloves garlic minced
- 1 cup heavy cream
- 1 cup freshly grated Parmesan cheese
- Salt to taste
- Freshly ground black pepper to taste
- Pinch of nutmeg optional, but adds warmth
For Serving (Optional)
- 8 oz zucchini noodles shirataki noodles, or your favorite low-carb pasta
- Grilled chicken shrimp, or sautéed vegetables (optional)
Step 1: Prep Your Ingredients
Mince the garlic finely so it releases maximum flavor.
Grate your Parmesan cheese fresh—this makes a huge difference in texture and taste.
If using zucchini noodles or other low-carb pasta, have them drained and ready.
Pro Tip: Keep all ingredients within reach before starting; this sauce cooks quickly, and you don’t want to be scrambling!
Step 2: Melt the Butter and Sauté Garlic
Place the butter in a medium saucepan over medium heat.
Once melted, add the minced garlic and sauté for 30–45 seconds until fragrant.
Pro Tip: Don’t let the garlic brown—it can turn bitter. Stir constantly for even cooking.
Step 3: Add the Cream
Pour in the heavy cream gradually, stirring as you go to combine with the butter and garlic.
Let it simmer gently for 2–3 minutes until slightly thickened.
Pro Tip: Keep the heat medium to low; too high and the cream can separate.
Step 4: Incorporate the Parmesan Cheese
Gradually add the grated Parmesan, whisking continuously until fully melted and smooth.
Season with salt, pepper, and a pinch of nutmeg if desired.
Pro Tip: Whisk continuously to prevent lumps and ensure a silky, smooth sauce.
Step 5: Toss with Your Pasta or Serve Over Veggies
Add your cooked low-carb pasta or vegetables to the sauce and toss gently until coated.
If using protein like chicken or shrimp, fold it in at this stage for a complete meal.
Pro Tip: Don’t overheat once the Parmesan is added; high heat can make the sauce grainy.
Step 6: Serve and Enjoy
Plate your healthy Alfredo pasta immediately, garnishing with extra Parmesan or freshly cracked black pepper if desired.
Enjoy warm, creamy comfort without the carb overload!
