Can You Freeze Pesto?

Can you freeze pesto?

Yes, pesto freezes excellently and is one of the best ways to preserve summer basil. The combination of ingredients makes pesto particularly freezer-friendly: olive oil (a natural preservative) coats the basil and prevents oxidation; Parmesan cheese adds fat content for protection; pine nuts (or other nuts) are stable; garlic is naturally stable in oil. All pesto variations freeze well: classic basil pesto (Genovese style); sun-dried tomato pesto; arugula pesto; spinach pesto; kale pesto; cilantro pesto; parsley pesto; sage pesto; mint pesto; nut-free pesto (with seeds instead); vegan pesto (with nutritional yeast); pesto rosso (red, with tomatoes); pistachio pesto. Frozen pesto lasts 4-6 months for best quality at 0°F (-18°C); safe indefinitely. After thawing or use from frozen: pesto retains its color, flavor, and texture remarkably well; the herbs stay green; the cheese melts smoothly into hot dishes. Pesto is the perfect 'oil-cube' solution for preserving herbs that would otherwise turn dark in the freezer.

How do you freeze pesto?

Ice cube trays are the gold standard for pesto. Method 1: ice cube trays (best method). Make pesto fresh; spoon into ice cube trays; freeze until solid; transfer cubes to labeled freezer bags. Each cube equals 1-2 tablespoons - the perfect amount for pasta servings or sauces. Method 2: muffin tins. For larger portions (1/4 cup per serving): spoon pesto into muffin tins; freeze; transfer pucks to labeled freezer bags. Method 3: freezer bags. Place pesto in freezer bags; press flat; freeze; break off pieces as needed.

How do you use frozen pesto?

Frozen pesto is used directly from the freezer for most applications. For pasta (best use): drop 1-2 frozen pesto cubes per serving into hot drained pasta; toss while the residual heat melts the pesto; the cubes melt evenly and coat the pasta. For pizza: spread thawed pesto on pizza dough as base sauce; bake as usual. For sandwiches: thaw in refrigerator 1-2 hours; spread on bread for caprese sandwiches, paninis, or grilled cheese. For salad dressings: thaw pesto and whisk into vinaigrettes; thin with a little lemon juice and oil. For soups: drop pesto cubes into hot soup; melt and stir for flavor boost. For appetizers: thaw and serve with crusty bread or crackers. Don't expect to use frozen pesto for: fresh basil garnish on cold dishes; raw caprese salad with thin pesto drizzles. The flavor is best in cooked applications.
