Kitchen Equipment to Make Stuffed Summer Squash with Sausage
- Large skillet or nonstick frying pan. The skillet can double as the mixing bowl or you can dump everything into a large bowl to combine the ingredients for the filling.
- Sharp knife and chopping board.
- Measuring cups and measuring spoons.
- 13×9-inch baking dish or rimmed baking sheet.
- Cheese grater.

Recipe Variations, Tips and Substitutions
- Cheese – You can use shredded cheese in a bag purchased from the grocery store but I like to grate my own. Use a nice parm or nice brick of parmesan reggiano in addition to shredded low moisture mozzarella cheese, Asiago cheese, monterey jack, cheddar colby jack cheese or sharp cheddar cheese. Pre-shredded Italian cheese comes in several varieties or you can use your favorite.
- Protein – You can use use ground chicken, turkey sausage or spicy chorizo for a Mexican mix for the filling.
- Fresh Herbs – You can garnish with basil, parsley, oregano or thyme.
- Spice – You can use crushed red pepper flakes for a little heat.
- Veggies – You could toss in diced red bell pepper or mushrooms in the sausage drippings, to change the flavor profile.
- Bread – I really love the texture fresh bread gives to the filling. If you’re in a hurry, you could use breadcrumbs i.e. panko bread crumbs or use croutons to a quick alternative. When doing so there’s no need to saute in butter and you may need to add one beaten egg to help the mixture hold together.
Tips and Tricks for Making Summer Squash
- Keeping Squash Upright – Use a sharp knife to cut a sliver from the peel side of the squash halves to stabilize it. This should help them remain upright while baking and prevent the squash from rolling around.
- Use a Steamer – The squash for this recipe can also be steamed, if that’s your preference. Place them into the basket of a steamer over simmering water and cook until the tip of a knife inserted into the thickest portion glides in easily. Adjust the time according to the size of the squash.
- Don’t Overcook the Squash – When steaming the squash halves initially make a special effort to cook just until fork tender so, you’ll be able to remove the seeds easily, and blot dry with paper towels before stuffing.
- Easier Clean-Up – You can use a baking pan or cookie sheet lined with parchment paper or tinfoil for easier cleanup.
Storage and Leftovers
- Leftovers – Store leftover Italian Sausage Stuffed Summer Squash in an airtight container chilled in the refrigerator for up to 3 days.
- Reheating – Reheat individual servings in the microwave.
- Freezer – I don’t recommend freezing this squash as the texture can change when thawing in the fridge.

Thanks Melissa, loved your recipie. I never get tired of trying different combinations of meats, cheeses, and spices with summer squash and zucchini. We grow and eat a whole lot of both so I’m always looking. I’m from Maryland and also catch our own crabs all summer and into late October. My most requested summer meal is a casserole we do with garden zucchini, onions, heirloom tomatoes, fresh crabmeat, and Italian cheeses.
Hi John, your casserole featuring garden vegetables and Maryland crab has GOT to be a winner! I’m so happy you enjoyed this thanks so much.
Hi: I’ve been making this dish for years and my husband loves it. I use italian sausage out of the casings, green peppers, chopped up and onions. I cover with shredded mozzerella and grated parmesan and then add a small can of italian canned sauce. Pop it in the oven for 1/2 hr. It’s like pasta in a vegetable!
Perfect recipe, I changed nothing.
Thanks so much!
Do you think it would be good with chicken. My husband can’t eat sausage. I always looking for recipes that are low in carbs. This recipe looks so good. We love squash and zucchini. I’m making this tonight, thanks for sharing this one. You always post the best looking recipes. Thanks for sharing this.
I think you could adapt this with beef or chicken, sure.
Looks wonderful. Going out to pick up some cheese. What do you use for the bread cubes? Cut up French bread?
Yes, french bread will work, as well as just about any dense bread will do fine.
That looks so tasty! Thanks for the shout-out for my recipe!
You bet, Kalyn, thanks!
