Taco Grilled Cheese already brings bold, cheesy comfort, so serving it with something crisp or bright helps round out every bite. Garlic Green Beans with Parmesan add freshness without stealing the spotlight, giving you a savoury side that lightens the richness of the sandwich.

If you want something more indulgent, Browned Butter Parmesan Roasted Potatoes deliver crispy golden edges that pair perfectly with the taco filled crunch of the grilled cheese. For a side with a little flair, Honey Roasted Butternut Squash & Brussels Sprouts With Bacon brings sweetness, saltiness and texture that turns this simple sandwich meal into something special.

Tips For Making Taco Grilled Cheese

  • Freshly grated cheese melts better than bagged, so I always grab a block when I can. It makes the pull apart moment so much more satisfying.
  • A light brush of butter or oil on the bread gives you that perfect golden crunch, the kind you hear before you taste.
  • Try not to overstuff the sandwiches, even if it is tempting. Too much filling makes flipping a little messy, and we want every bite inside the bread.
  • Medium heat is your friend here. Slow melting equals gooier cheese and beautifully browned bread.

Cover the pan with a lid for the first minute of cooking. The trapped heat encourages a smooth, even melt through the center.

Use moderate amounts of taco mince and press the sandwich gently with a spatula while cooking. Overfilling makes flipping messy.

Yes. Brush the outside of the bread lightly with butter or oil and cook an extra minute per side until crunchy.
