The colder and shorter days are upon us, but that doesn’t mean we have to give up on our grills or our healthy food. Quite the opposite, actually.
Fall grill meal prep is my favorite healthy meal prep. Probably because I love Fall food a lot. Like a lot, a lot.
When I meal prep fall recipes, I usually opt for pan meals, one-pot meals, Slow Cooker Freezer Meals or grilled meals. My grilled meals usually include grilled vegetables and healthy grilled chicken. I like to keep things simple and let the Fall flavors shine.
However, you know I like my healthy food tasty so my fall dinner ideas have to fit in 3 categories ---> clean, healthy, and delicious. Duh. There’s nothing like being excited for your meal prep dinners that have tons of flavor.
What I love about my make-ahead meals is that you can easily store them in airtight containers in the fridge and you have everything ready to grab for lunch or dinner the whole week.
This easy fall grill meal prep will provide you a week's worth of delicious, healthy grilled chicken, grilled sweet potatoes, grilled Brussel sprouts, and grilled butternut squash plus high protein and high fiber quinoa for the base and a cashew dressing that is out of this world.
You can store these separately for a buffet style meal prep or you can pair them with quinoa and top them with dried cranberries and raw pepitas and a healthy drizzle of our cashew apple cider dressing to bring all the flavors together. That’s my favorite way to do it and OMG, I love the Fall goodness in this fall grill meal prep.
Sounds about YUM, right?

How Long Does Meal Prep Last?
It may seem like a lot of work, but it’s actually very easy to prep everything. It also doesn’t take a lot of time since you’ll be doing more things at the same time. Here's basically how the whole process of meal prep works for this Fall Meal Prep on the Grill recipe:
- Start with the marinade.
- While the chicken is marinating in the fridge, soak the cashews so they are soft when you’ll be blending them later. The cashews have to stay in the water for at least an hour.
- I like to add a base to my Fall meal prep bowls. I usually go for quinoa or brown rice. So while the chicken is marinating and the cashews are soaked in water, I cook the quinoa in a saucepan for about 20-25 minutes.
- Now it’ time for prepping the veggies.
- At this point, we can start grilling the chicken, the butternut squash, and half of the sweet potatoes. I cook them over direct heat for approximately 6-8 minutes. Then flip over and cook on the other side until the chicken is cooked through and the sweet potatoes and squash are tender.
- Remove them from the grill and add the Brussel sprouts and the rest of the sweet potatoes. Cook for approximately 5-8 minutes, then flip and cook again for additional 4-6 minutes.
- While the last veggies are on the grill, we can make the cashew apple cider dressing. The dressing will be drizzled over our delicious grilled veggies and grilled chicken.
Okay! Now we have all our veggies and chicken grilled on our awesome Weber grill. We have the quinoa base ready, and the creamy dressing done so all we have to do is arrange everything in our meal prep containers.
Everything takes about an hour and a half. Which is pretty good considering you have a week worth of Fall dinners ready!
