Trader Joe’s Butternut Squash Mac and Cheese Recipe

This is one of my favorites for fall – trader joe’s butternut squash mac and cheese recipe!

It’s that time of year! Let’s bring our favorites to the Thanksgiving table! Some of my favorite recipes include stuffing, cranberry sauce, mashed potatoes, roasted vegetables, and creamy Butternut Squash Mac n’ Cheese. 

Honestly, I could eat this Copycat Trader Joe’s Butternut Squash Mac and Cheese dish any time of year, but I especially love making it in October and November. Butternut Squash and winter squashes are so festive and fun in the fall, and they are delicious in this dish. Best of all, this pasta dish has a creamy sauce and is better than the frozen mac and cheese version from Trader Joe’s. I love how this recipe utilizes a kitchen blender to create a creamy and decadent sauce without loads of cheese rather it is filled with veggies!

Let me tell you how I make this recipe!

 

Butternut Squash Mac n’ Cheese Ingredients

Elbow Macaroni: I often opt for traditional macaroni for this recipe however, you can use a different short pasta shape such as penne, rigatoni, fusilli, farfalle, radiatori, or orecchiette. 

Butternut Squash: I use a can of squash puree (for convenience) in this recipe but you can use fresh, homemade roasted butternut squash puree too. 

The creamy squash is a flavorful and healthy addition to this sauce. It is loaded with nutrients like beta carotene (a precursor of Vitamin A). Squash also has a beautiful, golden-yellow color, excellent for this vibrant Mac n’ Cheese, and has a subtle sweetness I love. 

*THE SECRET INGREDIENT* Riced Cauliflower: This is my secret ingredient!

You can’t taste the cauliflower with all the cheese, pasta, and squash flavors. Cauliflower helps to make the sauce creamy and comforting. It also gives the sauce its signature velvety smooth texture after blending.

Cheese: I use 2 different cheeses in this recipe. I wouldn’t say I like to use pre-shredded cheese rather I shred my cheese. 

In this recipe, I use high-quality sharp cheddar. I usually add at least one more cheese addition to my casserole. You can try Mozzarella or Gouda, but for this recipe, I used Greyure. Greyure makes for a creamy rich sauce and I love how it mingles with the cheddar.

What’s special about this Macaroni and Cheese recipe is its many variations. The cook can mix and match cheeses.

Cheeses: I refer to this article by Better Homes & Gardens to help with my cheese selection. 

More Flavor: Another fun option? Add a spicy element such as Harissa, jalapenos, or other peppers.

Veggies: Use veggies such as spinach, green beans, brussels sprouts, and tomatoes to make this pasta more veggie-packed.

Pasta: Even the pasta can be changed up! Make the recipe gluten-free with some simple ingredient swaps like gluten-free macaroni.
