Brown Butter Butternut Squash Casserole with caramelized onions and a buttery cracker crust is a fall recipe that’s absolutely incredible! It’s perfect for Thanksgiving but it’s so good you’ll want to make it all year long.
Full disclosure, this casserole is so good that it might just take center stage among all the sides at Thanksgiving. Everyone knows that the turkey is not really the star of that food-centric holiday because it’s actually all about the side dishes! This new dish is going to be a wonderful addition to my Thanksgiving Day menu this year and my guests are sure to love it.
I was inspired to make my version of this casserole after watching a cooking show on tv. I’ve never been much of a fan of butternut squash, mostly because it’s such a pain to prep. Now that most grocery stores sell prepared squash that’s peeled and cut into chunks, all of my excuses have been thrown out the window. What intrigued me most about the recipe was the brown butter and the caramelized onions. Those are two amazing ingredients on their own and I knew that combining them with the slightly sweet, mild squash would be amazing. I combined the browned butter, squash, onions then added in my own touches of dried thyme and a Ritz cracker topping. After baking the casserole for an hour, my house had filled with a mouthwatering aroma that assured me this was going to be one special side dish. Man, oh man, was I right!

How To Make Brown Butter Butternut Squash Casserole
This casserole is easy to make but there are a couple of critical steps that must be done correctly for the dish to turn out. First, place the squash (cut into about 1-inch cubes) into a 9″ deep-dish pie pan or 8×8 casserole dish. Next, melt a tablespoon of butter in a medium-size skillet. Add in the onions and cook on medium-low heat until they are golden brown, about 6 to 8 minutes. Add the onions to the squash.
Now it’s time to brown the butter. This takes a little bit of time and mostly patience. Add the remaining butter to the skillet and have heat set to medium. Cook the butter until it begins to brown, 3 to 4 minutes. The butter will foam and separate so be careful to watch it. It should brown, not burn. If it does burn, you’ll need to start over. Pour the butter over the butternut squash and onions and toss. Sprinkle on thyme, salt, and pepper. Cover casserole and bake for 50 minutes.
Lastly, crush a sleeve of Ritz butter crackers. Remove the casserole from the oven and sprinkle the crackers over the top. Return dish to the oven uncovered and cook an additional 15 minutes until crackers are golden brown. Let casserole cool for 5 minutes and serve!
