Equipment

  • Medium saucepan
  • Wooden Spoon or Silicone Spatula
  • Measuring Cups & Spoons
  • Grater
  • Knife & cutting board
  • Colander

Ingredients
  

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)

Instructions
 

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!
