This vegetarian Mexican Stuffed Acorn Squash is easy as it is delicious. It's filled with sauteed onions, hearty vegetables, rice and beans and are baked to golden perfection. A simple yet tasty weeknight meal.
Acorn squash is a winter squash that resembles acorns, hence the name. They are perfectly sized to hold individual servings of pretty much anything, such as this Mexican-inspired vegan stuffing. Because these stuffed acorn squash halves are meatless, the cooked flesh of the acorn squash will add some bulk and substance.
Mexican Stuffed Acorn Squash
These Mexican Stuffed Acorn Squash requires a few steps, but none that are difficult. In fact, the entire dish comes together effortlessly in under an hour. You can make the Mexican-inspired stuffing while the squash is roasting in the oven.
Then scoop that delicious stuffing which features sauteed onions, hearty veggies, rice and beans, into the roasted squash halves and bake until perfect golden perfection. The cheese is totally optional and omitting it makes these Mexican Stuffed Acorn Squash vegan and vegetarian.
A drizzle of sour cream (again, omit if dairy-free), chopped cilantro and green onions, and zesty pico de gallo completes this easy meal.
How to Bake Acorn Squash
Cooking acorn squash is easier than you think. The hardest part is actually cutting the squash lengthwise in half so be sure your knife is sharp and work surface steady.
I prefer to cook my acorn squash as I do all my squashes - perfectly roasted in the oven.
Follow these easy steps to roast acorn squash:
- Preheat oven to 425 degrees Fahrenheit and line a rimmed baking sheet with parchment paper.
- Cut the squash with a sharp knife lengthwise from tip to stem. (Tip: it's easiest to first pierce the squash in the center along one of the depression lines. Cut through to the tip on one side. Then spin the squash around and finish by cutting through the top portion to the stem)
- Using a large spoon, scoop out the seeds and discard or save to roast at a later time.
- Place the cleaned squash halves cut side up on the parchment-lined pan. Drizzle some avocado oil over the squash or use an avocado-oil cooking spray for ease. Season with sea salt. Turn the squash halves cut-side down and bake for 30-40 minutes just until fork tender.
Vegan Stuffed Acorn Squash
These Mexican Stuffed Acorn Squash halves are meatless and if you omit the cheese, it could easily pass as a vegan meal.
As much as I love acorn squash, the stuffing is clearly the star of this dish. It hails sauteed onions, bell pepper, tomato, rice, corn and beans all tossed in appropriate seasonings. After everything is combined, it is then scooped into the roasted squash bowls, topped with cheese (optional) and baked to bring all the flavors together.
I personally love cooking rice in bone broth for added nutrition. You can use this method to cook perfect rice in the Instant Pot or use any leftover rice from a previous meal.
The stuffing also calls for 1 cup of frozen corn and black beans. If you are cooking your own beans, I always recommend that you soak them first and cook in large batches in the Instant Pot. Beans freeze exceptionally well and can be frozen in pre-measured sizes (1 cup, 2 cups, etc..)
A standard can of beans typically holds a little over 2 cups of beans, so you will have some leftover that can be used for a future recipe.
After filling the squash halves with the Mexican mixture, you may find that you are left with some leftovers. Transfer any leftover stuffing mixture to a sealed container and keep in the refrigerator for up to 5 days. It can be added to chopped romaine lettuce and dressed with Ranch or a drizzle of avocado oil and lime for an easy salad.
