Juicy Dijon Garlic Grilled Chicken Breasts
I’ve been in the mood for salads these days, and this juicy Dijon garlic grilled chicken is exactly what I want piled over a big bowl of crisp mixed greens. The quick salt brine keeps the chicken breasts tender and moist, while Dijon mustard, garlic, black pepper, and a touch of olive oil add plenty of savoury flavour. It’s an easy BBQ chicken breast recipe that feels light and fresh but still makes a salad satisfying enough for dinner. Add cucumber, red onion, tomatoes, avocado, and your favourite creamy dressing, and you have a simple summer meal that never feels boring.
Short Description of the Recipe
These juicy Dijon garlic grilled chicken breasts are soaked in a quick salt brine, coated with olive oil, and seasoned with Dijon mustard, garlic powder, black pepper, and a little salt. They cook quickly on the barbecue and come off the grill tender, lightly charred, and full of savoury flavour. Slice the chicken over mixed greens for an easy summer dinner, or serve it with your favourite side dishes.

Why It’s Good
The simple brining step makes a real difference. Chicken breasts can dry out quickly on the grill, but soaking them first helps the meat stay juicy and tender. The Dijon garlic seasoning adds plenty of flavour without overpowering the chicken, and the edges develop those delicious golden grill marks.
It’s also an easy, flexible recipe. The sliced chicken tastes especially good with crisp mixed greens, cucumber, tomatoes, red onion, avocado, and a creamy salad dressing. Light, but still filling.

When to Serve It
Serve this easy grilled chicken breast recipe for summer lunches, casual family dinners, weekend barbecues, or meal-prep salads. It’s a great choice when you’re in the mood for something fresh but still want a satisfying meal.
The chicken is also handy for picnics, wraps, sandwiches, rice bowls, and quick lunches during the week. Grill a little extra. The leftovers are very good cold over a mixed green salad the next day.
These juicy Dijon garlic grilled chicken breasts turned out beautifully tender, with golden charred edges and plenty of savoury flavour in every slice. The quick salt brine really helps keep the chicken moist, while the Dijon mustard, garlic, olive oil, and black pepper create a simple seasoning that works with almost anything. I like slicing the grilled chicken before serving because you can see just how juicy it is—and it makes it perfect for piling over mixed greens, adding to wraps, or serving with an easy summer side dish.
Tips and Tricks
- Brine the chicken breasts first. Even an hour in salted water helps grilled chicken stay tender and juicy. It is a small step, but I notice a real difference once the chicken is sliced.
- Pat the chicken very dry. Any extra moisture can stop the outside from browning properly. Dry chicken gives you better grill marks and a more flavourful crust.
- Keep the chicken an even thickness. If one end is much thicker, gently pound it before brining. This helps the whole breast cook at the same rate.
- Preheat the barbecue well. A hot, clean grill at about 400°F to 450°F helps prevent sticking and gives the Dijon garlic chicken those golden, lightly charred edges.
- Do not keep flipping it. Let the chicken cook undisturbed for a few minutes before turning. That is when the nice grill marks develop.
- Check the temperature early. Large chicken breasts can take a little longer, but overcooking dries them out quickly. Remove the chicken when the thickest part reaches 165°F.
- Let it rest before slicing. Five minutes is enough. Cutting it immediately lets all those good juices run out onto the plate.
Ingredient Notes
- Chicken breasts: Choose two good-sized boneless, skinless chicken breasts. Breasts that are close in size will cook more evenly on the grill.
- Salt brine: Cold water and kosher salt create a simple chicken brine that helps season the meat from the inside and keeps it moist during grilling.
- Olive oil: A light coating helps the seasoning stick and encourages browning. You do not need a lot.
- Dijon mustard: Dijon adds a mild tang and savoury depth without making the grilled chicken taste strongly of mustard.
- Garlic powder: Garlic powder coats the chicken more evenly than fresh garlic and is less likely to burn over the high heat of the barbecue.
- Black pepper: Freshly ground black pepper gives the chicken a little warmth and works especially well with the Dijon seasoning.
- Red pepper flakes: These are optional, but a small pinch adds gentle heat. I keep it light when serving the chicken over mixed greens.
- Fresh herbs: Parsley, thyme, or rosemary can be added for extra flavour. Fresh herbs also make the sliced grilled chicken look lovely when served.
Variations
- Cowboy butter grilled chicken: Add smoked paprika, dried parsley, red pepper flakes, and a little lemon zest to the Dijon garlic seasoning for a bolder, buttery-style flavour.
- Lemon herb chicken breasts: Mix fresh lemon juice, thyme, parsley, and garlic powder into the olive oil. This version is especially good sliced over mixed greens.
- Spicy Dijon chicken: Add cayenne pepper or extra red pepper flakes for a little heat. Start small—you can always add more.
- Honey Dijon grilled chicken: Stir 1 tsp honey into the Dijon seasoning for a lightly sweet, tangy crust. Watch the grill closely because honey can brown quickly.
- Italian herb chicken: Use dried basil, oregano, and parsley with the garlic powder for an easy Mediterranean-style grilled chicken.
- Grilled chicken thighs: Boneless, skinless chicken thighs also work well and stay naturally juicy. They may need a few extra minutes on the barbecue.
Storage Tips
- Store leftover Dijon garlic grilled chicken in an airtight container in the refrigerator for up to 3–4 days.
- Let the chicken cool before refrigerating, but do not leave it sitting at room temperature for more than 2 hours.
- Keep the chicken breasts whole until you are ready to use them. I find they stay a little juicier than when they are stored already sliced.
- Reheat gently in a covered skillet with a splash of water or chicken broth. High heat can dry grilled chicken out fast.
- The leftovers are also delicious cold. Slice the chicken thinly and add it to mixed green salads, wraps, sandwiches, grain bowls, or quick meal-prep lunches.
- Freeze cooked grilled chicken for up to 3 months. Wrap each breast well, place it in a freezer-safe container, and thaw overnight in the refrigerator.
Juicy Dijon Garlic Grilled Chicken Breasts
Equipment
- Outdoor barbecue or gas grill
- Medium bowl or shallow container for brining
- Measuring cups and spoons
- Paper towels
- Silicone brush or clean hands for seasoning
- Long-handled grilling tongs
- Instant-read meat thermometer
- Cutting board
- Sharp chef’s knife
- Serving plate or platter
Ingredients
Salt Brine
- 2 chicken breasts large, boneless and skinless
- 4 cups cold water or enough to cover the chicken
- 2 tbsp kosher salt
- Dijon Garlic Seasoning
- 1 tbsp olive oil
- 1 tbsp Dijon mustard
- 1 tsp garlic powder
- ½ tsp black pepper freshly ground
- ¼ tsp salt
- 1 Pinch red pepper flakes optional
Instructions
- Place the chicken breasts in a bowl or shallow container. Add enough cold water to completely cover the chicken and stir in the kosher salt.
- Cover and refrigerate for about 1 hour. This simple chicken brine helps the breasts stay juicy while grilling.
- Remove the chicken from the brine and discard the liquid. Pat the chicken thoroughly dry with paper towel.
- Drizzle both sides with olive oil. Rub with Dijon mustard, then season evenly with garlic powder, black pepper, salt, and optional red pepper flakes.
- Clean and lightly oil the barbecue grates. Preheat the grill to medium-high heat, approximately 400°F to 450°F.
- Place the chicken breasts on the hot grill. Cook for 3–4 minutes without moving them, then flip and cook for another 3–4 minutes.
- If the chicken breasts are especially large or thick, turn them once more and continue grilling until the thickest part reaches 165°F.
- Transfer the grilled chicken to a clean plate and let it rest for 5 minutes before slicing. Resting makes a noticeable difference—it keeps those juices in the chicken instead of on the cutting board.
Notes
- Brining the chicken breasts for about 1 hour helps create juicy grilled chicken that stays tender on the barbecue.
- Pat the chicken completely dry after brining so the Dijon garlic seasoning sticks and the outside develops better grill marks.
- If the chicken breasts are very thick, gently pound the larger end for more even cooking.
- Preheat the barbecue to 400°F–450°F before adding the chicken. A properly heated grill helps prevent sticking.
- Cooking time will vary depending on the size and thickness of the chicken breasts.
- Use an instant-read thermometer and cook until the thickest part reaches 165°F. Overcooking is the main reason grilled chicken turns dry.
- Let the Dijon garlic grilled chicken breasts rest for 5 minutes before slicing to keep the juices inside the meat.
- Slice the chicken against the grain for tender pieces that are easy to serve over mixed greens.
- This easy BBQ chicken breast recipe is delicious warm or chilled in salads, wraps, sandwiches, and meal-prep bowls.
- Store leftover grilled chicken whole when possible. It tends to stay juicier than chicken stored already sliced.
