How to keep mason jar salads fresh all week
Mason jars are excellent for meal prep because layering creates a barrier between wet and dry ingredients. The trick is to place the densest, most moist items at the bottom and the lightest, most delicate items at the top.
Layering order for best results: dressing (if you choose to include it), cooked chicken, other moist toppings, romaine, cheese, and croutons on top. I prefer to keep the dressing separate and add it when serving to avoid sogginess; you can also store croutons separately if you want them extra-crisp. Properly assembled, these mason jar salads will stay fresh in the refrigerator through the workweek, making grab-and-go lunches effortless.
How to make shortcut grilled chicken Caesar mason jar salads
This recipe leans on shortcuts, so the steps are straightforward.
1. Trim the chicken breasts and slice each breast horizontally to create four thinner pieces. Place the pieces in a bowl.
2. Combine the contents of a marinade packet with a splash of vinegar and a splash of water, stirring until the mixture is uniform. Toss the chicken in the marinade to coat.
3. Preheat a grill pan over medium-high heat and lightly oil it. Grill the chicken for about 5 minutes per side, or until the internal temperature reaches 165°F (74°C). Remove from heat and let the chicken rest.
4. When cool, chop the chicken into bite-sized pieces.
5. Assemble the mason jar salads: add an even layer of chopped chicken to the bottom of each jar, followed by chopped romaine. Top with shaved Parmesan and croutons. If you’re using dressing, portion 2 tablespoons per jar into small containers or keep a bottle in the fridge to add at serving time.
That’s it—four salads ready for the week.
