You’re going to start by slice off the top of the acorn squash, taking off about 2 inches from the top. Peel the top and dice it up. I ended up about 1/2 cup of squash and that was the perfect amount. Slice off just enough from the bottom end so it can stand up nice and sturdy. Scoop out the seeds from the inside of the squash and discard. Place the squash on a parchment-lined baking sheet and preheat the oven to 350 degrees F.
To a small saucepan, set over medium heat, add the oil. When hot, add the squash and a pinch of salt. Allow to cook, stirring frequently, for about 5 minutes. Next, add the shallot, garlic and pasilla chile. Cook for an additional 3 to 5 minutes. Remove from heat and set aside.
To the squash, add a spoonful of the chile/squash mixture and then top with a handful of cheese. Repeat this until you’ve worked your way through all of the cheese and squash filling. Press the cheese all the way down into the squash and add any more you can to the top—you want this to be cheesy!
Transfer to the oven to bake for 15 minutes. Remove it from the oven and using a teaspoon, give it a stir. (I know this sounds weird but you really need to do this so it’s all melty.) And then return it to the oven to bake for an additional 10 minutes.
Serve with chips or crackers. I topped mine with some cilantro and a squeeze of lime.
If you don’t want to serve this in a squash, you can add everything to a 8-inch baking dish and bake it up!
