Butternut Squash Stuffed Shells with Sage Brown Butter Sauce

Updated 9/11/17: The photographs have been updated on this post. It is originally from November, 2012, and the content of the post remains the same, so may be outdated.

This weekend we had a little girls weekend at my moms house with my Aunt Penny and her good friend Megan. Like every girls weekend should be, it was filled with lots of eating,

drinking,

crafting,

and more eating.

When preparing for girls weekend, we delegated different duties to each person, and I gladly volunteered to pick out our menu for our Saturday night dinner. When I saw these butternut squash stuffed shells, I knew they would be perfect.

The stuffing is a combination of mashed butternut squash, ricotta, garlic, spinach, Parmesan cheese, and a little bit of lemon zest. As if that wasn’t enough, the shells are finished off with a brown butter and sage sauce. I know, again with the brown butter. Seriously, it’s amazing stuff.

If you like butternut squash, you have to make this. It is perfect for serving to guests. The squash filling could easily be prepared ahead of time, and you could even let everyone join in on the fun of filling the shells. Paired with a fall-inspired salad and some garlicky, buttery french bread, it was absolutely delicious.

Ingredients

1 medium butternut squash peeled, de-seeded and chopped into 1" cubes
2 tbsp olive oil
2 cups ricotta cheese
1 cup Parmesan cheese divided use
2 cloves garlic minced
1/2 cup frozen spinach thawed, drained, and squeezed dry
1 egg
1 lemon juiced and zested
1/2 cup 1 stick butter
10 fresh sage leaves
salt and pepper to taste
1 package jumbo shells about 24 shells

Instructions

Preheat oven to 425 degrees F.
Line large baking sheet with aluminum foil.
Toss butternut squash in olive oil, then season with salt and pepper, and arrange onto prepared baking sheet.
Roast in preheated oven for 20-25 minutes, until squash is tender.
Let cool.
Bring large pot of water to boil and cook shells al dente (so about 2-3 minutes less than package directions)
While water is boiling, you can brown the butter. Do this in a small saucepan over medium heat, stirring constantly until butter turns an amber color. Once it is amber, remove from heat and add sage leaves and juice from the lemon. Let cool.
In large bowl, add butternut squash and mash with potato masher or you can puree with immersion blender to obtain a smooth consistency.
You should get about 2 cups of squash puree.
If you get more than 2 cups, you can put the extra in a plastic baggie and freeze for later use.
To the bowl with mashed butternut squash, add ricotta, 1/2 cup of Parmesan cheese, garlic, spinach, egg, 1 tsp of lemon zest, and salt and pepper.
Now you are ready to assemble the shells.
Butter a 9x13" casserole dish.
Preheat the oven to 350 degrees.
Stuff the shells carefully with about 2-3 tbsp of the squash mixture.
Don't get too caught up with exact amounts, just do about a heaping spoonful into each shell.
I tried to stuff as much filling as I could into each shell because the filling is so good!
Once shells are all filled and arranged in casserole dish, drizzle half of the brown butter over them, then sprinkle with remaining 1/2 cup of Parmesan cheese.
Bake in preheated oven for 20-25 minutes, until the shells are heated through and the cheese is melted.
Once done baking, drizzle with remaining brown butter.
Enjoy!
