A Chicken Pesto Sandwich is a delicious combination of juicy chicken, herby pesto, and melted cheese, all layered between bread. Most traditional versions are not Keto-friendly due to high-carb bread and hidden sugars. However, with the right ingredients and techniques, you can make a Keto chicken pesto sandwich that tastes even better than the original. Let’s learn the best recipes and tips.

What Makes a Chicken Pesto Sandwich Keto-Friendly?

A traditional chicken pesto sandwich is high in carbohydrates because of using bread made with grains. To make this sandwich Keto-friendly, you need to use low-net-carb substitutes.

By tweaking the traditional chicken pesto sandwich recipe and using Keto bread, you can manage the macronutrients and make a low-carb, high-fat, and moderate-protein sandwich.

To remain Keto-friendly, the recipes we are going to learn here follow these rules:

  • Net carbs under 6g per serving
  • Healthy fats
  • No sugar or refined flour
  • Whole, minimally processed ingredients

Why Pesto Works on Keto?

Classic basil pesto is naturally Keto-friendly because it contains:

  • Olive oil (fat)
  • Basil (very low carb)
  • Parmesan cheese
  • Garlic (minimal carbs)
  • Pine nuts (small amounts)

As long as you avoid added sugars and cashews, pesto fits into a Keto Diet. You can use the following recipes to make Keto-friendly pesto.

Ultra-Creamy Keto Pesto

To make the pesto sauce ultra-creamy, add 2 tbsp avocado oil mayo or 2 tbsp heavy cream (not dairy-free).

Nut-Free Keto Pesto

To make nut-free Keto pesto, use the above recipe but replace nuts with extra Parmesan or sunflower seeds (slightly higher carbs but still Keto).

The lowest-carb nut options include macadamia nuts (~0.3g), pine nuts (~0.6g), and Walnuts (~0.6g). But avoid cashews because they have about 1.6g.

Common Keto Pesto Mistakes

  • Using store-bought pesto with sugar
  • Using cashews instead of pine/macadamia nuts
  • Skipping oil (fat is essential on Keto)
  • Over-blending (turns bitter)

Tips for Storing Keto Pesto

  • Fridge 5-7 days and top with olive oil to prevent browning.
  • Freeze up to 3 months. The ice cube tray works great.
