Key Culinary Techniques & Science
- Roasting Sweet Potatoes: Slow-roasting at 375°F (190°C) ensures even cooking, caramelizing natural sugars for depth of flavor while keeping the flesh tender.
- Sautéing Mushrooms: Cooking mushrooms on medium-high heatdrives off moisture, concentrating their umami-rich taste.
- Emulsifying Pesto: Blending basil, nuts, garlic, and oil creates a stable emulsion, with Parmesan adding savoriness and lemon juice balancing richness.

Step-by-Step Instructions
1. Roast the Sweet Potatoes
- Preheat oven to 375°F (190°C).
- Scrub potatoes, pat dry, then prick with a fork. Rub with olive oil and salt.
- Place on a baking sheet and roast for 45–55 minutes, until tender when pierced with a knife.
Pro Tip: For crispier skins, increase heat to 400°F (200°C) for the last 10 minutes.

- Heat olive oil in a pan over medium-high heat.
- Add mushrooms and cook until browned (~5 min).
- Stir in garlic, rosemary, salt, and pepper; cook 1 minute.

3. Make the Basil Pesto
- In a food processor, blend basil, pine nuts, garlic, and Parmesan.
- Drizzle in olive oil while blending until smooth.
- Stir in lemon juice, then season to taste.
Pro Tip: Add a splash of water if the pesto is too thick.
4. Assemble & Serve
- Slice roasted sweet potatoes open and fluff the insides with a fork.
- Spoon in the mushroom-spinach filling, drizzle with pesto, and garnish with extra feta and basil.
Troubleshooting Advice
- Potatoes too hard? Roast longer or microwave for 2–3 minutes before baking.
- Filling too watery? Cook mushrooms longer to evaporate excess moisture.
- Pesto too bitter? Balance with more Parmesan or a pinch of sugar.
Creative Variations
