🥘 What you need for this recipe
Ingredients and Substitutions

- Delicata Squash - The squash is usually available in fall, and most stores carry it. Look for a yellow squash with green vertical stripes. If not in season or you can't find it, try acorn squash as a substitute!
- Meatless Sausage - Use your favorite vegetarian sausage, preferably Italian-spiced. If you're not vegetarian, regular sausage is fine too!
- Arugula - Arugula is what I had, but any leafy green will work! Spinach is a great choice too, just chop it roughly before cooking.
- Mushrooms - Finely diced crimini mushroom caps, but portobello or shiitake are fine too!
- Parmesan - Optional, use vegan parmesan if making this dish vegan.
Tools and Equipment
- Sharp Knife
- Sheet Pan
- Medium Nonstick Pan
📋 How to make Stuffed Delicata Squash
Step 1: Prepare the Squash
Preheat the oven to 425º Fahrenheit.
Begin by using a very sharp knife to cut off the top stem of the squash. Then, very carefully cut the squash in half longways.
Use a metal spoon to scrape the seeds out of the inside until completely clean.



Spray or drizzle the inside of the squash with olive oil, along with the sheet pan.
Roast at 425º Fahrenheit for 20 minutes, until the squash is fork tender.
Remove and set to the side.
Step 2: Make the Filling
Crumble the meatless sausage with your fingers, or mince with a knife.
Finely chop the mushroom caps and give the arugula a rough chop.
Remove rosemary from the stems and roughly chop it into small pieces.
In a nonstick pan, add about 1 tablespoon olive oil and the crumbled sausage.
Sauté until browned.



Add the chopped mushrooms and continue to sauté until cooked.
Remove the pan from the heat and add rosemary and arugula and grated parmesan.
Stir to combine until the arugula has wilted and the parmesan is mostly melted.
Step 3: Stuff and Roast
Turn the oven to 300º Fahrenheit.
Gently scoop the sausage filling into the cavity of the squash.
Fill until just slightly over the top of the squash.


Top with more grated cheese and put back into the oven until the parmesan starts to melt and/or brown.
Optional, but you may want to broil for 2-3 minutes to brown the cheese further.
Serve warm and enjoy!
