Stuffed Shells with Butternut Squash Ingredients
There’s only a handful of ingredients needed for this recipe, here’s a quick rundown of the list with tips and substitution ideas for your best stuffed shells.
- Butternut Squash – Use a 3 – 4 lb. butternut squash. For ease, you can always pick up pre-cut squash in the produce dept. You’ll want about 6 cups – 4 cups for the sauce and 2 cups to stuff.
- Cashew Ricotta – We’ll be using this easy cashew ricotta recipe which uses just a handful of ingredients. It’s totally amazing and will satisfy everyone!
- Spinach – Use fresh or frozen. I used about 2 – 3 ounces of fresh, roughly chopped. You can use a 10 oz. package of frozen spinach, just be sure to let it thaw and squeeze it well to remove the water.
- Jumbo Shells – You’ll need at least 18 jumbo shells, but it’s always best to make a few more just in case one falls apart.
- Thyme – Use fresh or dried thyme. Feel free to change up the herb with sage or oregano.
- Garlic – You’ll find garlic in the ricotta so if you want to skip this clove of garlic, you won’t miss it much. Or you can use 1/2 teaspoon garlic powder in its place.
- Red Pepper Flakes – Adds a little heat and pairs well with the sweetness of the squash, adjust the amount to suit your taste.
- Salt – My all-time favorite salt is pink mineral salt (affiliate link) which naturally contains essential minerals and trace elements the body needs. It’s delicious and a little goes a long way.
- Oil – Use your favorite oil, we’ll just be using it to roast the butternut squash.
- Liquids – I simply used water for the butternut squash sauce and it was delicious! Feel free to use broth or a combo of broth and water.
