Today is National Acorn Squash Day. As a kid, I had no idea there were so many different types of squash!

This recipe — Portobello and Sage-Stuffed Acorn Squash — is one that you can enjoy as the weather gets cool (in some places) as we head into fall.

Portobello and Sage-Stuffed Acorn Squash

This protein-packed stuffed acorn squash provides a healthy and tasty alternative to traditional holiday side dishes. Crisp pancetta, rich Portobello mushrooms, sweet dates, and aromatic sage bring fabulous, yet diverse, flavor to every bite. As an added bonus, the lentils and walnuts make it more filling, so maybe you’ll be able to stop at just one piece of pumpkin pie this holiday season!

Servings 6


  • 3 acorn squash cut in half and seeds removed
  • 3 T. extra virgin olive oil divided
  • 3-4 cloves garlic finely minced
  • 4 oz. pancetta diced
  • lbs. Portobello mushrooms roughly chopped
  • ½ medium yellow onion thinly sliced
  • 1 c. green lentils cooked
  • 1 1/2 T. fresh sage finely chopped
  • ¼ c. dry red wine
  • 1/3 c. dates roughly chopped
  • ¼ c. walnuts chopped
  • ¼ c. Parmesan cheese freshly grated
  • Sea salt and pepper to taste

Also need:

  • Non-stick cooking spray


  • Position oven rack to the center position, then preheat oven to 400°F. Spray a large baking dish with non-stick cooking spray and set aside.
  • Place the acorn squash halves cut side up in the prepared baking dish and brush cut edges with one tablespoon olive oil. Season with salt and black pepper, to taste. Place baking dish on center rack in preheated oven and roast for 40 minutes, or until the squash is fork-tender.
  • While the squash is roasting, heat the remaining olive oil in a large skillet over medium heat. Add minced garlic and pancetta and cook, stirring occasionally, until slightly browned, approximately 2-3 minutes.
  • Add chopped mushrooms and cook, stirring occasionally, until they start to brown, approximately 4-5 minutes. Add sliced onions and continue cooking, stirring once or twice, for another 3-4 minutes.
  • Stir green lentils, fresh sage, and red wine into the skillet. Cook, stirring occasionally, until mixture thickens, approximately 8-10 minutes. Remove from heat and stir in the chopped dates and toasted walnuts. Season with salt and black pepper, to taste. Set aside.
  • When ready, remove cooked squash from oven and cool slightly before filling each half with the Portobello mushroom mixture. Sprinkle each half with some freshly grated Parmesan cheese.
  • Return stuffed squash to oven for another 5-10 minutes, or until heated through and the cheese starts to melt. Remove from oven and serve immediately. Enjoy!
