While nowhere near as glamorous or greasy as its crispy companion, grilled chicken is starting to increase in popularity as it rides the wave of health-conscious dining.

But seared chicken isn't masked by a delicious fried coating, so it has to be good to pass muster.

We tried grilled-chicken sandwiches from major fast-food chains — Burger King, McDonald's, Wendy's, and Chick-fil-A — to find out which is best.

5. Burger King Tendergrill

According to Burger King's menu, this chicken is marinated and seasoned with "pepper and herbs" — yet in reality, it tastes of utter nothing. The bun is weak and underwhelming and prone to flattening. And with the sandwich coming in at 470 calories — the highest of any on this list by a long shot — its healthiness is dubious at best.

This is a chicken sandwich in the midst of an existential crisis. Is it meant to be an enjoyable, flavorful item or merely a bland vehicle for protein delivery? The chicken itself is dry, stringy, and tough. The lettuce and tomato are pallid, and the mayonnaise oversteps its boundaries in every bite. This sandwich leaves one in tangy despair.

4. McDonald's Artisan Grilled Chicken

This sandwich is part of the "Artisan" chicken revamp McDonald's released in 2015 along with the crispy fried version. The grilled white-meat breast fillet is topped with lettuce, tomato, and a vinaigrette dressing, all within McDonald's "artisan" bun.

The chicken, in a word, is rubbery. It's not all that flavorful, even with the mystery vinaigrette that quickly becomes a messy, drippy hassle. The slightly sweet bun is a mismatch with grilled chicken — it works better with the saltier fried chicken and best with a savory beef patty. It's a middle-of-the-road, disenchanting sandwich with little imagination at best.

3. Wendy's Grilled Chicken Sandwich

By comparison, Wendy's grilled chicken is an adventurous departure. The recently recalibrated recipe involves honey mustard and tart spring greens beneath a nutty bun. I'm not normally a fan of multigrain buns, but this one is fairly unobtrusive.

The chicken is dense and marinated well with a clean, herbal flavor that is complemented well by the sharp spring greens — chard, arugula, spinach, and romaine. The honey mustard is sweet, but only just; it actually has a rather strong bite.

2. Chick-fil-A Grilled Chicken Club

1. Chick-fil-A Grilled Chicken

Just a rosy red tomato slice and some lettuce within the inoffensive multigrain bun is all that's needed to make this simple sandwich hugely enjoyable. Plus, it has the lowest calorie count of the whole list, clocking in at 310 calories.

Chick-fil-A just plain knows how to do chicken.

The chain is popular mostly for its fried chicken — sandwiches, nuggets, strips — but even its grilled chicken is delicious. With recent chicken overhauls from McDonald's and Wendy's, it's clear that the fast-food giants are trying to make inroads in Chick-fil-A's market, but they have a long way to go.
