Grilled Butternut Squash Tacos With Chipotle-Lime Crema

These grilled butternut squash tacos turn one of fall’s most familiar vegetables into a colorful, satisfying outdoor meal. The squash is seasoned with chili powder, cumin and smoked paprika, grilled until tender and lightly charred, then piled into warm corn tortillas with crunchy cabbage, avocado and pickled onions.

A cool chipotle-lime crema balances the natural sweetness of the squash with smoky heat and fresh citrus. Whether you are looking for a vegetarian taco recipe, an easy fall dinner or something different to cook on the grill, these tacos deliver plenty of flavor without trying to imitate meat.

How to Prepare Butternut Squash for the Grill

Rinse the outside of the squash under running water before cutting or peeling it. Place it on a stable cutting board and use a sharp chef’s knife to remove the stem and bottom ends.

Peel the squash, cut it in half lengthwise and scoop out the seeds. Slice the solid neck into approximately ½-inch-thick planks or half-moons. Cut the rounded bottom section into similarly thick pieces.

Keeping the pieces reasonably consistent in thickness helps them cook at the same rate. If you prefer to avoid cutting a whole squash, purchase peeled butternut squash and cut it into large, grill-friendly slices.

How to Make Grilled Butternut Squash Tacos

1. Preheat the Grill

Preheat a clean grill to medium-high heat, approximately 400–425°F. Leave part of the grill at a lower temperature or set it up for indirect cooking in case the squash begins browning before it becomes tender.

2. Season the Squash

Place the squash slices in a large bowl. Add the olive oil, chili powder, cumin, smoked paprika, garlic powder, salt and black pepper.

Toss until every piece is lightly and evenly coated. The oil helps prevent sticking and allows the spices to adhere to the squash.

3. Grill Until Tender

Place the squash directly on the heated grill grates. Grill for approximately 4–6 minutes per side, turning carefully with tongs or a thin spatula.

The squash is ready when it has visible grill marks and can be pierced easily with a fork. If it is browning too quickly, move it to the cooler side of the grill and close the lid until the center becomes tender.

Transfer the cooked squash to a cutting board and let it cool for several minutes. Chop it into bite-size pieces for the tacos.

4. Make the Chipotle-Lime Crema

Combine the sour cream or Greek yogurt, minced chipotle pepper, adobo sauce, lime juice, honey and salt in a small bowl.

Taste the crema before adding additional chipotle. The heat level can vary considerably between brands and individual peppers.

For a thinner drizzle, stir in water one teaspoon at a time until the crema reaches the desired consistency.

5. Warm the Tortillas

Place the tortillas on the grill for approximately 15–30 seconds per side, just until warm and flexible. Do not leave them unattended because small tortillas can toast very quickly.

Wrap the warm tortillas in a clean kitchen towel or place them in a covered tortilla warmer until serving.

6. Assemble the Tacos

Add shredded cabbage to each tortilla, followed by the grilled butternut squash. Top with avocado, pickled red onions, cilantro and chipotle-lime crema.

Finish with crumbled cheese or toasted pumpkin seeds if desired. Serve immediately with fresh lime wedges.

Easy Quick-Pickled Red Onions

If you do not have prepared pickled onions, thinly slice half of a red onion and place it in a heat-safe bowl or jar.

Combine ½ cup warm water, ½ cup vinegar, 1 tablespoon sugar and 1 teaspoon salt. Pour the mixture over the onions and let them sit for at least 20–30 minutes. Drain before adding them to the tacos.

Tips for Better Grilled Butternut Squash Tacos

• Cut even slices: Pieces with similar thickness will finish cooking at approximately the same time.
• Do not cut the squash too thin: Very thin pieces can soften excessively and become difficult to turn.
• Oil the squash, not the entire grill: A light coating helps prevent sticking without creating unnecessary flare-ups.
• Use two heat zones: Begin over direct heat for grill marks, then move the squash to indirect heat if it needs more time.
• Control the chipotle: Start with one pepper and increase the heat only after tasting the crema.
• Warm the tortillas last: They taste best when served directly from the grill.
• Add contrasting textures: Cabbage, pumpkin seeds and pickled onions balance the soft grilled squash.

Easy Variations

Add Black Beans

Add seasoned black beans for additional texture and a more substantial taco. Warm the beans in a grill-safe pan while the squash cooks.

Make the Crema Dairy-Free

Use an unsweetened dairy-free yogurt or cashew-based sour cream. Check the consistency and adjust the lime and water as needed.

Make the Tacos Vegan

Use dairy-free crema, omit the cheese and choose agave instead of honey. Avocado and toasted pumpkin seeds provide richness without dairy.

Add Grilled Corn

Grill corn beside the squash, cut the kernels from the cob and sprinkle them over the tacos for additional sweetness and charred flavor.

Turn It Into a Taco Bowl

Serve the grilled squash over rice, quinoa or shredded lettuce. Add the same cabbage, avocado, onions and crema used for the tacos.

Can You Make These Tacos Ahead?

The crema and pickled onions can be prepared one or two days ahead and refrigerated in separate covered containers.

The squash is best directly from the grill, but it can be cooked ahead and reheated in a skillet, grill basket or covered grill-safe pan. Store the tortillas and fresh toppings separately so they maintain their texture.

What to Serve With Butternut Squash Tacos

These tacos pair well with:

• Grilled corn with lime and cotija
• Black beans or refried beans
• Cilantro-lime rice
• Avocado and tomato salad
• Fresh pineapple salsa
• Chips with guacamole or roasted salsa

Frequently Asked Questions

Do I need to cook the squash before grilling?

No. Slices approximately ½ inch thick can cook directly on a preheated grill. Use indirect heat to finish them if the exterior browns before the center becomes tender.

Can I use precut butternut squash?

Yes. Larger precut pieces can be threaded onto skewers or cooked in a grill basket. Very small cubes may fall through standard grill grates.

Can I roast the squash instead?

Yes. Roast seasoned squash on a sheet pan at approximately 425°F until browned and tender, turning it during cooking. It will not have the same grilled flavor but will work well with the remaining toppings.

How spicy is the chipotle-lime crema?

One chipotle pepper creates a noticeable but manageable heat level. Start with half a pepper for a milder sauce or add extra adobo sauce for more smoky heat.

Are these tacos gluten-free?

They can be. Use corn tortillas that are labeled gluten-free and verify the labels on the chipotle peppers, seasonings and other packaged ingredients.

What other squash can I grill for tacos?

Acorn, delicata and kabocha squash can also work. Peeling requirements, cooking time and texture will vary by variety.
