Weeknight Dinners

How to turn a jar of store-bought pesto into five different weeknight dinners

How to turn a jar of store-bought pesto into five different weeknight dinners

I keep at least one jar of store-bought pesto in my fridge most weeks. Not because I don’t like making it from scratch—I do—but because a good pesto jar is one of those tiny shortcuts that transforms chaos into dinner. Over time I’ve learned that a single jar can stretch into multiple meals without feeling repetitive. Here are five weeknight dinners I make again and again that all start with that same green jar of pesto.

Why jarred pesto is a weeknight hero

Jarred pesto is concentrated flavor in a jar: basil, garlic, cheese, nuts, olive oil. It’s already seasoned, bright, and fat-rich, which means it can do heavy lifting in a recipe. A few tablespoons will dress pasta, turn roasted vegetables into a main, or act as an instant sauce for chicken. I’m not trying to hide the fact it’s store-bought—brands like Barilla, Kirkland, or a local artisanal jar will do—but I do a couple of small things to make it feel homemade and more versatile.

How I bulk up a jar to make it stretch

Before the recipes: here are my go-to tricks for stretching pesto so it feeds more people, tones down salt when needed, or changes the texture depending on the dish.

  • Thin with pasta water or cream: For pasta and grain bowls I add a splash of hot pasta water to loosen the pesto; for a richer sauce, a tablespoon of cream or plain yogurt works nicely.
  • Brighten with lemon: A squeeze of lemon juice wakes up jarred pesto and cuts through the oiliness.
  • Bulk with veggies or beans: Toss roasting vegetables or stirred-in cannellini beans to create a more substantial dish without using more pesto.
  • Toast nuts and add herbs: Toasted pine nuts, walnuts, or almonds add crunch; a handful of fresh herbs (parsley, mint) changes the flavour profile if basil tastes tired.
  • Pesto Pasta with Quick Veg and Crispy Breadcrumbs

    This is the “fast and familiar” weeknight pasta. It takes 20 minutes and uses things you probably already have.

  • Cook 12 oz (about 340 g) pasta—penne, fusilli, or farfalle work—reserve 1 cup pasta water.
  • While pasta cooks, sauté 2 cups of quick-cooking veggies (cherry tomatoes halved, spinach, frozen peas) in 1 tbsp olive oil until just tender.
  • Turn off the heat. Stir in 1/2 cup jarred pesto and 1/3 cup reserved pasta water. Add pasta and toss. If it’s too thick, add more pasta water a tablespoon at a time.
  • For texture, toast 1/2 cup panko in 1 tbsp olive oil until golden and sprinkle on top. Finish with a squeeze of lemon and extra parmesan if you have it.
  • Swaps: Use gluten-free pasta or swap panko for crushed crackers. Add cooked shredded rotisserie chicken for protein.

    Pesto Chicken Sheet Pan (hands-off weeknight)

    One pan, minimal cleanup. This is what I make when I’ve been out with the kids and want dinner in the oven while we decompress.

  • Preheat oven to 425°F (220°C). On a sheet pan, place 4 bone-in chicken thighs (skin on) or boneless breasts.
  • Rub each piece with 1 tbsp jarred pesto (about 1/3 cup total). Scatter quartered baby potatoes, halved carrots, and red onion wedges around the chicken. Drizzle everything with a little olive oil, salt, and pepper.
  • Roast 25–35 minutes until chicken is cooked through and potatoes are tender. Spoon any extra pesto from the pan over the finished chicken before serving; a small handful of arugula tossed on the pan at the end brightens the plate.
  • Tip: Use boneless thighs to shorten cooking time. Swap chicken for salmon fillets—reduce oven temp to 400°F and roast 8–12 minutes depending on thickness.

    Pesto Grain Bowl with Roasted Veg and Chickpeas

    My fallback for a balanced, make-ahead dinner. Make extra grains on the weekend and this bowl assembles in minutes.

  • Cook 1 cup quinoa or farro according to package instructions.
  • Toss 1 can drained chickpeas and 2 cups chopped vegetables (zucchini, bell pepper, cauliflower florets) with 1 tbsp olive oil, roast at 425°F for 20–25 minutes.
  • Mix 3 tbsp pesto with 1–2 tbsp lemon juice and 1–2 tbsp water to loosen. Toss with warm grains, top with roasted veg and chickpeas.
  • Optional: crumbled feta or a soft-boiled egg for extra protein.
  • Make-ahead note: Roast veg and cook grains a day ahead. Reheat and assemble in under 10 minutes on busy nights.

    Pesto Flatbread Pizza — Ten-Minute Dinner

    This is my kids’ favorite because they can customize their side like grown-up pizza. Use store-bought naan or flatbreads.

  • Preheat oven to 450°F (230°C). Spread 2 tbsp pesto over each flatbread.
  • Top with shredded mozzarella, thinly sliced tomatoes, a sprinkle of cooked sausage or sliced mushrooms, and a handful of baby spinach.
  • Bake directly on the oven rack for 6–8 minutes until cheese is melted and edges are crisp. Finish with a drizzle of olive oil and a few basil leaves.
  • Swap: Use dairy-free cheese, skip meat for a veggie version, or add dollops of ricotta for richness.

    Pesto-Stuffed Chicken Roll-Ups (30-minute dinner, looks fancy)

    When I want something a bit more special but still honest and quick. These are easy to customize—great for picky eaters because the flavors are familiar.

  • Butterfly 4 chicken breasts and pound thin. Spread 1 tbsp pesto on each, top with a slice of mozzarella and a few spinach leaves.
  • Roll up and secure with toothpicks. Sear in a hot skillet with 1 tbsp oil for 2 minutes per side, then transfer to a 375°F (190°C) oven for 12–15 minutes until cooked through.
  • While chicken rests, deglaze skillet with 1/4 cup white wine or chicken broth, add remaining 1–2 tbsp pesto and 1 tbsp butter to make a quick pan sauce. Spoon over sliced roll-ups.
  • Allergy note: Replace cheese with dairy-free alternative and use nutritional yeast for a savory hit if avoiding dairy.

    Final tips for making a jar of pesto go further

    Buy a jar size that matches how often you cook—if you use pesto weekly, a larger jar saves money. If you’re worried about waste, freeze pesto in tablespoon portions on a baking sheet and then transfer to a zip-top bag so you can thaw exactly what you need.

    When the jar is nearly finished, don’t toss the oil: mix that last bit into vinaigrette or sautéed greens. And don’t be afraid to tweak salt, lemon, or add fresh herbs—small adjustments make jarred pesto feel more like something you’d make in your own kitchen.
