Ingredients
- 2 medium acorn squash
- 2 tbsp olive oil
- 1, finely diced shallot
- 8 oz, sliced cremini mushrooms
- 1 tbsp fresh thyme leaves
- 2 tbsp, finely chopped fresh sage
- 1 tbsp butter
- 1/4 cup, chopped pecans
- 1/2 tsp coarsely ground black pepper
- 1/4 tsp salt
Instructions
- Step 1: Preheat oven to 400°F (200°C). Cut squash in half lengthwise, scoop out seeds, and brush cut sides with 1 tbsp olive oil. Place cut-side down on a parchment-lined baking sheet; roast for 30 minutes until fork-tender.
- Step 2: While squash roasts, heat remaining 1 tbsp olive oil in a skillet over medium heat. Add diced shallot and cook for 3-4 minutes until translucent, then add sliced mushrooms and cook for 8 minutes until golden and moisture evaporates.
- Step 3: Stir in thyme, chopped sage, butter, 1/4 tsp salt, and 1/2 tsp black pepper. Remove from heat, fold in pecans, and spoon mixture into hollowed squash halves. Return to oven for 5 minutes to warm through.
