Ingredients
- 1 pound medium acorn squash (about 1 1/2 squash)
- 1 tablespoon olive oil
- 1/4 cup Parmesan cheese (finely grated)
- 1/2 tablespoon garlic (minced)
- Salt and pepper (to taste)
- 1/4 cup pistachios (plus additional, for garnish)
- 1/4 cup walnuts (plus additional, for garnish)
- 3/4 cup roughly chopped sage (tightly packed)
- 1/2 cup roughly chopped parsley (tightly packed)
- 1 cup roughly chopped kale (tightly packed)
- 2 tablespoons fresh thyme (loosely packed)
- 1 teaspoon lemon zest (packed)
- 1 teaspoon fresh lemon juice
- 1/2 cup Parmesan cheese (finely grated)
- 1 teaspoon garlic (minced)
- 7-9 tablespoons olive oil
- Salt and pepper (to taste)
Instructions
- Step 1: Preheat your oven to 425°F and spray a rimmed baking sheet with cooking spray.
- Step 2: Halve the acorn squash and scoop out the seeds. Slice it into 3/4-inch half moons.
- Step 3: In a large bowl, toss the squash with 1 tablespoon olive oil until well coated. Add 1/4 cup Parmesan cheese and 1/2 tablespoon minced garlic, then toss again.
- Step 4: Arrange the squash in a single layer on the prepared baking sheet. Season with salt and pepper. Bake until golden brown and tender, about 30 minutes.
- Step 5: While the squash roasts, spread the pistachios and walnuts in a single layer on a small baking tray. Toast in the oven at 425°F for 5-7 minutes until lightly toasted, watching closely to avoid burning.
- Step 6: Transfer toasted nuts to a small food processor and pulse until broken into small pieces.
- Step 7: Add sage, parsley, kale, and thyme to the nuts in the food processor. Pulse until finely chopped.
- Step 8: Add lemon zest, lemon juice, 1/2 cup Parmesan cheese, and 1 teaspoon minced garlic. Process until well combined.
- Step 9: With the processor running, gradually stream in 7 to 9 tablespoons olive oil until the pesto is smooth and emulsified. Season to taste with salt and pepper.
- Step 10: When the squash is done, transfer it to a large serving dish and toss gently with about half of the pesto, ensuring even coating.
- Step 11: Garnish with additional toasted nuts and serve with the remaining pesto on the side.
Tips & Variations
- For a nuttier flavor, toast the walnuts and pistachios slowly over medium heat on the stovetop instead of the oven.
- Swap kale with spinach or arugula for a milder pesto taste.
- Add a pinch of red pepper flakes to the pesto for a subtle spicy kick.
- Use toasted pine nuts instead of pistachios and walnuts for a classic pesto variation.
Storage
Store any leftover roasted squash and pesto separately in airtight containers in the refrigerator for up to 3 days. Reheat the squash gently in the oven or microwave before serving. Pesto is best served fresh but can be stirred with a little olive oil before using to restore its texture.

FAQs
Can I make the pesto ahead of time?
Yes, pesto can be made a day in advance and stored in the refrigerator. Keep it in an airtight container with a thin layer of olive oil on top to prevent browning.
Can I use frozen kale for the pesto?
Fresh kale works best for texture and flavor, but if using frozen kale, thaw and squeeze out excess moisture before processing to avoid a watery pesto.

Ingredients
Roasted Acorn Squash
- 1 pound medium acorn squash (about 1 1/2 squash)
- 1 tablespoon olive oil
- 1/4 cup Parmesan cheese (finely grated)
- 1/2 tablespoon garlic (minced)
- Salt and pepper (to taste)
Sage-Kale Pesto
- 1/4 cup pistachios (plus additional, for garnish)
- 1/4 cup walnuts (plus additional, for garnish)
- 3/4 cup roughly chopped sage (tightly packed)
- 1/2 cup roughly chopped parsley (tightly packed)
- 1 cup roughly chopped kale (tightly packed)
- 2 tablespoons fresh thyme (loosely packed)
- 1 teaspoon lemon zest (packed)
- 1 teaspoon fresh lemon juice
- 1/2 cup Parmesan cheese (finely grated)
- 1 teaspoon garlic (minced)
- 7–9 tablespoons olive oil
- Salt and pepper (to taste)
Instructions
- Preheat Oven: Preheat your oven to 425°F (220°C) and lightly spray a rimmed baking sheet with cooking spray to prevent sticking.
- Prepare Squash: Cut the acorn squash in half and scoop out the seeds. Slice the halves into 3/4-inch thick half-moon pieces for even roasting.
- Roast Squash: Place the squash pieces in a large bowl and toss with 1 tablespoon olive oil until evenly coated. Add 1/4 cup Parmesan cheese and 1/2 tablespoon minced garlic, tossing again to combine. Spread the squash pieces in a single layer on the prepared baking sheet, sprinkle with salt and pepper to taste, then roast in the oven for about 30 minutes, or until golden brown and tender.
- Toast Nuts: While the squash is roasting, arrange pistachios and walnuts (1/4 cup each) in a single layer on a small baking tray. Toast them at 425°F for 5-7 minutes until lightly browned and fragrant, keeping a close eye to avoid burning.
- Process Nuts: Transfer the toasted nuts to a small food processor and pulse until broken down into small pieces but not fully powdered.
- Blend Herbs: Add the roughly chopped sage, parsley, kale, and fresh thyme to the food processor with the nuts. Process until the herbs are finely chopped and mixed. Then add lemon zest, lemon juice, 1/2 cup Parmesan cheese, and 1 teaspoon minced garlic, processing again until well combined.
- Emulsify Pesto: With the food processor running, slowly stream in 7 to 9 tablespoons olive oil until the pesto achieves a smooth, spreadable consistency. Taste and adjust seasoning with salt and pepper as desired.
- Serve: Once the roasted squash is done, transfer it to a large serving dish. Gently toss the squash with about half of the pesto to coat evenly. Sprinkle additional toasted nuts on top for garnish, and serve the remaining pesto on the side for extra flavor.
Notes
- Keep a close watch on nuts while toasting to prevent burning, as ovens vary.
- For a nut-free version, substitute nuts with pumpkin seeds or omit entirely and increase olive oil slightly.
- Use fresh herbs for the best flavor; dried herbs will alter the taste significantly.
- This dish works well warm or at room temperature, making it suitable for make-ahead meals or gatherings.
