This roasted vegetable couscous meal prep has become my weekly ritual for ensuring I have delicious, nutritious lunches ready to go. The combination of sweet roasted vegetables, fluffy couscous, and your choice of protein makes for satisfying meals that actually keep me looking forward to lunch time.
I first made this recipe during a particularly hectic work week when I knew I wouldn't have time to prepare lunches daily. The aroma of those roasting vegetables filled my kitchen and my family kept wandering in asking when dinner would be ready even though I was prepping for the upcoming week!

Step-by-Step Instructions
- Roast the Vegetables:
- Chop Roma tomatoes zucchini bell pepper and red onion into chunks that will roast evenly. I find that 1inch pieces work perfectly as they shrink during cooking. Toss everything with olive oil salt and pepper making sure each piece is lightly coated this ensures even caramelization. Roast at 400°F for about 45 minutes stirring occasionally to prevent burning. The vegetables should become soft with caramelized edges which concentrates their flavors dramatically.
- Prepare the Couscous:
- Bring vegetable broth to a boil in a saucepan. The hot liquid will cook the couscous without any additional heat needed. Once boiling pour in the couscous stir once cover with a lid and remove from heat. Let it sit undisturbed for 5 minutes until all liquid absorbs. Fluff gently with a fork to separate the tiny grains and place in refrigerator to cool slightly while you prepare the protein.
- Cook Your Protein:
- For chicken mix softened butter with dried herbs spices and seasonings until you have a paste. Spread this mixture over chicken breasts ensuring they're evenly coated. This herb butter creates a protective layer that keeps the meat moist while infusing flavor. Bake until juices run clear and internal temperature reaches 165°F about 20 minutes. For chickpeas simply sauté in a skillet until golden and slightly crispy then toss with the same herb mixture minus the butter.
- Assemble Your Meals:
- Combine the cooled couscous roasted vegetables minced roasted garlic and fresh parsley in a large bowl. The still warm vegetables will gently wilt the parsley releasing its aromatics. Divide this mixture between four containers and top each with either sliced chicken or seasoned chickpeas. Add a small container of ranch dressing if desired for extra creaminess when serving.

The roasted garlic is my secret weapon in this recipe. After roasting they become sweet and incredibly mellow nothing like their raw counterparts. I always fish them out from the vegetable mix mash them into a paste and stir them throughout the couscous for little bursts of incredible flavor in every bite.
Storage Tips
These meal prep containers stay fresh in the refrigerator for up to four days making them perfect for weekly lunch planning. The flavors actually improve after a day as everything melds together. Keep the dressing separate until ready to eat to maintain the best texture of all components.
Make It Your Own
This recipe welcomes substitutions based on whatever vegetables are in season or in your refrigerator. Try sweet potatoes or cauliflower in fall butternut squash in winter or eggplant in summer. The cooking method remains the same regardless of which vegetables you choose just ensure they're cut to similar sizes for even cooking.

Serving Suggestions
While designed as a complete meal these components can be repurposed throughout the week. The roasted vegetable couscous makes an excellent side dish for grilled meats or can be stuffed into bell peppers with some cheese on top for a different dinner option. Add a squeeze of lemon juice just before eating to brighten all the flavors.
