Description

Stuffed acorn squash makes your lunch feel like a special occasion – and it’s also

meal-prep friendly.


Ingredients

Scale

Acorn Squash 

  • 3 medium acorn squash
  • 1 Tbsp olive oil
  • Sea salt and freshly ground pepper

Stuffing Ingredients 

  • 1 tsp dried sage
  • 3 cups cooked lentils
  • 8 oz (225 g) mushrooms, sliced
  • ½ yellow onion, chopped
  • 1 clove garlic, minced
  • ½ tsp sea salt
  • ½ tsp ground black pepper
  • 2 cups riced cauliflower
  • Sprinkle non-dairy cheese on top (optional)

Instructions

Prep the Squash

  1. Preheat your oven to 400°F/200ºC. Cut each squash in half and scoop out the seeds and fibrous center. Line a baking sheet with parchment paper and place the squash halves on it, cut side up.
  2. Brush each half with olive oil and sprinkle with salt and pepper. Roast for 30 minutes and then flip each half over and continue to roast for 15 minutes or until very tender. Remove from the oven and lower the oven temperature to 350°F/177ºC.

 

Make the Filling

  1. While the squash is roasting, heat a large skillet over medium-high heat.
  2. Add the sage and let cook, stirring constantly, for about 20-30 seconds.
  3. Add the mushrooms, onion, garlic, and salt. Cook, stirring frequently, until the onions are soft and the mushrooms begin to shrink, about 8-10 minutes.
  4. Add the cauliflower rice to the skillet and stir until combined. Then add the lentils and simmer for 5 minutes and remove from the stove.
  5. By now your squash should be done. Flip each one cut-side-up and spoon an equal amount of filling into each half.
  6. Optional – sprinkle the stuffed squash halves with non dairy cheese. Place back in the oven and bake for approx 5 minutes.
  7. Serve and enjoy!

Storage and Reheating Tips

To ensure your Stuffed Acorn Squash stays fresh and delicious, proper storage and reheating are key:

Storage

Once cooled, place any leftover stuffed acorn squash halves in an airtight container to retain their moisture and prevent flavor loss. Store them in the refrigerator for up to 3 days. If you plan to save portions for longer, wrap them tightly in plastic wrap or foil and place them in a freezer-safe container. They can be frozen for up to 2 months, making them a great make-ahead meal option.

Reheating

For the best texture and flavor, reheat the squash in a preheated oven at 350°F (177°C) for 10-12 minutes, or until heated through. This method helps maintain the crisp-tender squash texture and keeps the filling flavorful. If you’re short on time, the microwave is a convenient alternative—simply heat on medium power for 2-3 minutes, checking halfway to ensure even warming. For frozen squash, thaw in the fridge overnight before reheating.

Customization Ideas

This recipe is incredibly versatile, making it easy to tailor to your tastes or experiment with different flavor profiles:

For a Mediterranean Twist

Mix sun-dried tomatoes, olives, and crumbled feta cheese into the filling for a burst of tangy, savory flavors. These ingredients complement the sweetness of the squash beautifully while adding variety to the dish.

For Extra Crunch

Enhance the texture by sprinkling toasted walnuts, pecans, or pumpkin seeds on top before serving. Not only do these nuts add a satisfying crunch, but they also bring in healthy fats and a nutty richness that elevates the dish.

For Spice Lovers

Add a pinch of chili flakes, cayenne pepper, or smoked paprika to the filling for a kick of heat. The smoky or spicy notes pair well with the earthiness of the mushrooms and lentils, creating a more robust flavor profile.
