I’m developing a yearly obsession with delicious and user-friendly Delicata Squash, and I love this type of squash so much that today I’m reminding you to make this favorite Delicata Squash and Sausage Gratin. I make this every year when this tasty squash comes into season! If you like winter squash, I bet you’ll love this recipe as much as we did! 

I created this recipe by accident when Jake and I were trying a sausage and green pepper mixture stuffed inside Delicata Squash, and we ended up with far too much stuffing for the amount of squash we had. So we went to Plan B and made a casserole with the roasted squash, sausage-pepper mixture, and cheese.

Jake isn’t the biggest fan of winter squash but he agreed this gratin with sausage and Delicata Squash was really, really good. But please don’t wait too long to try this recipe, because Delicata Squash is only available for a few months in late summer and early fall, and soon it’s going to disappear from the store for another year.

What ingredients do you need for this recipe?

  • Delicata Squash
  • Olive Oil (affiliate link)
  • Italian Herb Seasoning (affiliate link)
  • salt and fresh-ground black pepper to taste
  • hot or mild Turkey or Pork Italian Sausage
  • onion
  • green bell pepper
  • grated Mozzarella cheese

What Makes Delicata Squash Different than other types of winter squash?

What makes Delicata Squash user-friendly and different from other winter squashes is the way you can eat the skin! How cool is that? Eating the skin makes it easier to prepare and adds fiber to reduce the net carbs.

Is Delicata Squash Low in Carbs?

Probably no winter squash is technically a low-carb ingredient, but Delicata Squash is lower in carbs and higher in fiber than many types of winter squash. Here’s more information about this attractive and delicious squash variety!

How to Make Delicata Squash and Sausage Gratin:

  1. Delicata can have either green or yellow strips like the photo above, top left.
  2. Cut the squash in chunks about an inch square, saving the ends to dice smaller for the sausage mixture.
  3. Toss squash with olive oil and Italian Herb Blend, then roast on a baking sheet at 400F/200C for about 25 minutes.
  4. While the squash is roasting, heat a little oil and then cook the sausage until it’s nicely browned; remove to a bowl.
  5. Add a little more oil and cook the diced onion and green pepper with a little more Italian herb blend. Add to bowl with the sausage.
  6. Cut up the ends of the squash into pieces about 1/3 inch squash and cook for a few minutes.
  7. Then heat the sausage, onions, peppers, and small pieces of diced squash together for a minute or two.
  8. Spray a large casserole dish with olive oil or non-stick spray.
  9. Put roasted pieces of squash in the dish and top with the sausage mixture and then a layer of grated cheese.
  10. Bake 20-25 minutes, or until all the ingredients are hot and the cheese is melted and starting to lightly brown. Serve hot and enjoy!

Delicata Squash and Sausage Gratin
Yield: 8 servings

Delicata Squash and Sausage Gratin

Prep Time 30 minutes
Cook Time 45 minutes
Total Time 1 hour 15 minutes

Delicata Squash and Sausage Gratin also has green bell pepper and cheese and this is a delicious easy casserole to make when it's Delicata Squash season.

Ingredients

  • 3 Delicata Squash, about 8 inches long each
  • 3 T olive oil, divided
  • 2 tsp. Italian Herb Blend, divided
  • salt and fresh-ground black pepper to taste
  • 19.5 oz. pkg. hot or mild Turkey Italian Sausage (see notes)
  • 1 medium onion, chopped
  • 1 large green bell pepper, chopped
  • 2 cups grated Mozzarella

Instructions

  1. Preheat oven to 400F/200C.
  2. Wash Delicata squash if needed and cut off the ends in a piece about an inch wide.
  3. Cut the squash in half lengthwise and use a sharp spoon to scrape out the seeds and discard. Cut the main part of the squash into pieces about 1 inch square and dice the end pieces into small pieces about 1/3 inch square. (The squash is not peeled before cutting it up; you eat it with the peel on.)
  4. Put the larger squash pieces in a bowl and toss with 1 tablespoon olive oil, 1 teaspoon Italian Herb blend, and salt and fresh-ground black pepper to taste. Put squash pieces on a baking sheet (spray with olive oil or non-stick spray if you need it with your baking sheet.)
  5. Roast squash about 25 minutes, or until it’s softened but not completely cooked.
  6. While squash cooks, heat 1 tablespoon olive oil in a large non-stick frying pan over medium-high heat. Squeeze the sausage out of the casing and cook until it’s nicely browned, breaking apart with a turner (or potato masher) as it cooks. (Most turkey sausage will release some liquid; just cook until it’s evaporated and the sausage will start to brown.)
  7. Remove the browned sausage to a bowl, add a little more olive oil, and cook the onion and green pepper over medium-high heat until it’s cooked and starting to slightly brown.
  8. Add the other teaspoon of Italian Herb Blend and cook 1 minute more. Remove the onion-pepper mixture to the bowl with the sausage.
  9. Add the rest of the oil (about 2 teaspoons) and add the smaller squash cubes. Saute over medium high heat until the squash is quite soft and starting to slightly brown, about 7-8 minutes. Add the sausage, onions, and peppers back into the pan and cook just until everything is heated through.
  10. Remove the roasted squash cubes from the oven, leaving oven on. Spray a large glass or crockery casserole dish with olive oil or non-stick spray. (I used a dish that’s about 10 inches x 12 inches, but any size that’s close to that will work.)
  11. Put the hot squash in the bottom of the casserole dish, topping it with the hot sausage/onions/peppers mixture. Sprinkle with grated cheese.
  12. Bake uncovered about 20-25 minutes, or until the mixture is very hot and the cheese is completely melted and nicely browned. Serve hot.

Notes

I used my favorite Turkey Italian Sausage for this recipe.

This can be kept in the fridge for several days and reheated in the microwave or in a pan on the stove. I’m guessing it freezes well, although I have ever had any leftovers to freeze when I made it!
