Garden-Fresh Pesto for Winter
Preserving Basil for Cozy Winter Dishes with Easy Freezer Cubes
As the growing season draws to a close, our garden overflows with vibrant basil—holy, Thai, and sweet varieties, each bursting with unique aroma and flavor. Harvesting these fragrant leaves feels like capturing summer in our hands, ready to brighten our winter meals. This year, we’re transforming our basil bounty into a versatile pesto, perfect for freezing and enjoying in countless dishes. Here’s how we do it, along with creative ways to savor that pesto all winter long.
Basil Pesto Recipe
This pesto celebrates our garden’s diversity, blending three types of basil for a rich, aromatic sauce. It’s simple to make and freezes beautifully in silicone freezer trays for convenient, portioned cubes.
Note: We intentionally leave out Parmesan cheese in this base recipe to maximize versatility for different dishes. You can always add freshly grated Parmesan when using the pesto in your final dish.
Ingredients:
Fresh basil (mix of holy, Thai, sweet, or any preferred variety), about 2 cups packed
1.5 cups pine nuts
1 head of garlic, peeled
Olive oil, as needed (approximately 1/2 to 3/4 cup)
Salt, to taste
Black pepper, to taste
Equipment:
Food processor
Instructions:
Add fresh basil to the food processor.
Secure the lid on the food processor.
With the food processor running, slowly add the following through the top chute:
1.5 cups pine nuts
Peeled cloves from 1 head of garlic
A steady stream of olive oil
A pinch of salt and black pepper
Continue processing and adding ingredients slowly, pausing to taste and check consistency.
Stop when the pesto reaches your desired texture and flavor balance.
Serve immediately or store in an airtight container in the refrigerator.
Preserving the Harvest
Using silicone freezer trays makes storing pesto a breeze, creating perfect portions for future meals. Each cube is ideal for tossing into recipes without thawing a whole batch. Once frozen solid, pop the cubes out of the tray and transfer to a labeled freezer bag for longer storage. These little green gems carry the essence of our garden, ready to elevate winter dishes with a burst of flavor.
5 Delicious Ways to Use Your Pesto Cubes
These recipes showcase the convenience of frozen pesto cubes—they thaw quickly, blend seamlessly into hot dishes, and bring instant flavor to everything from breakfast to dinner. Here are five of our favorite ways to use them:
Tomato Basil Soup
We recently shared a cozy recipe for garden-fresh tomato soup, elevated with a cube of this basil pesto swirled in just before serving for extra depth and aromatic complexity. Check out the full recipe here: From Garden to Freezer to Bowl.
Pesto Roasted Vegetables
Toss seasonal vegetables (like zucchini, bell peppers, and potatoes) with one to two thawed pesto cubes per pound of vegetables, a drizzle of olive oil, and a pinch of salt. Roast at 400°F (200°C) for 25-30 minutes until golden and tender. The pesto infuses a savory, herby kick, turning simple veggies into a standout side dish.
Pesto Grilled Cheese Sandwich
Spread a thawed pesto cube on the inside of your bread before assembling a grilled cheese sandwich. Pair with sharp cheddar or mozzarella for a melty, flavorful twist. Cook on medium heat until the bread is golden and the cheese is gooey—a quick lunch with a gourmet edge.
Pesto Pasta with Shrimp
Cook your favorite pasta (like linguine or penne) until al dente. In a pan, sauté shrimp with garlic and a splash of lemon juice. Toss the cooked pasta and shrimp with 1-2 thawed pesto cubes and a handful of cherry tomatoes. Sprinkle with Parmesan for a fast, restaurant-worthy dinner.
Pesto Breakfast Scramble
Whisk a thawed pesto cube into eggs before scrambling for a vibrant, flavorful breakfast. Add diced tomatoes, spinach, or mushrooms, and serve with toast or wrapped in a tortilla. It’s a quick way to bring summer’s freshness to your morning.
