A Healthy Chicken Enchilada Dinner

Enchiladas are a special family favorite in my house. The rich red sauce and tender chicken feel festive, but swapping tortillas for roasted spaghetti squash turns the dish into a lighter, veggie-forward dinner that still satisfies. It’s a great way to add more vegetables to the plate while keeping the familiar enchilada flavors.

What You’ll Need

The ingredient list is straightforward, making this a perfect weeknight option. Here’s what you’ll want on hand:

  • Spaghetti squash: A 2½-pound squash will serve four.
  • Olive oil: For brushing before roasting.
  • Salt and pepper: To taste.
  • Cooked chicken: Leftover shredded chicken works great; rotisserie or freshly cooked breasts are fine too.
  • Red enchilada sauce: Store-bought is convenient, but homemade works if you prefer.
  • Zucchini: Finely diced to add a mild, fresh texture.
  • Ground cumin: 1 teaspoon to add warm, smoky depth.
  • Chili powder: ½ to 1 teaspoon, depending on how spicy you like it.
  • Dried oregano: ½ teaspoon for an herbal note.
  • Cheese: Monterey Jack is shown here; pepper jack is a good spicier alternative.
  • Fresh cilantro: Chopped, for garnish.

How to Make Chicken Enchilada Spaghetti Squash Boats

The recipe starts with roasted spaghetti squash—simple to prepare and a great low-carb base for the enchilada filling.

  1. Roast the squash: Preheat the oven to 400°F. Line a baking sheet with parchment or foil. Cut the squash in half lengthwise and scoop out seeds and fibers. Brush the cut sides with oil, season with salt and pepper, and place cut-side-down on the baking sheet. Roast 35–40 minutes or until tender.
  2. Shred the squash: Let the halves cool enough to handle. Use a fork to scrape the strands away from the rind, leaving about a 1/4-inch border so the shells can hold the filling. Transfer the squash strands to a bowl and return the empty halves to the baking sheet.
  3. Prepare the enchilada mixture: Combine the shredded chicken and finely diced zucchini with the squash strands. Season with cumin, chili powder, oregano, salt, and pepper. Stir in 1 cup of red enchilada sauce.
  4. Assemble the boats: Divide the chicken-squash mixture into the two squash halves. Spoon the remaining enchilada sauce over the top and finish with shredded cheese.
  5. Bake: Return the stuffed squash to the oven and bake 10 minutes, until the cheese melts. For a golden finish, broil 1–2 minutes until lightly browned—watch closely to prevent burning.
  6. Serve: Remove from the oven, garnish with chopped cilantro, slice each half in two, and serve warm.

Tips for Success

These suggestions help streamline the process and offer simple variations:

  • Slow-cooker option: If you prefer not to roast, cook a whole spaghetti squash in a slow cooker for 3–5 hours—pierce it several times first.
  • Change the protein: Browned ground beef is a tasty alternative if you want beef enchilada boats.
  • Spaghetti-style version: Swap enchilada sauce for spaghetti sauce and use mozzarella for a pasta-inspired bake using the same squash base.

Serving Suggestions

These boats pair nicely with fresh, simple sides:

  • Salad: A crisp green salad or an avocado tomato salad complements the warm, cheesy boats.
  • Cowboy caviar: A hearty relish of beans, corn, avocado, and fresh veggies adds bright, zesty contrast.
  • Grilled pineapple: For a sweet-savory twist, grilled pineapple brings caramelized sweetness and acidity.

How to Store and Reheat Leftovers

  • Remove the filling from the shells before storing. Place the filling in airtight containers and refrigerate up to 3 days.
  • To reheat, warm the filling in a covered skillet over low heat until heated through, cheese-side up if possible to preserve the topping.

Can I Make This Ahead?

Yes. Assemble components ahead and freeze for later:

  1. Roast the squash, remove the strands, and discard the shells. Drain the strands and pack them into freezer bags for up to 6 months.
  2. Cook and cool the chicken-zucchini-enchilada mixture, then freeze in airtight containers for up to 3 months.
  3. To finish, thaw overnight, mix the squash and chicken mixtures, place in a greased casserole dish, top with cheese, and bake at 350°F until hot and bubbly.
