Easy Meal-Prep Healthy Chicken Stew with Winter Squash & Spinach
When the days grow shorter and the air turns crisp, nothing comforts me more than ladling thick, aromatic spoonfuls of this golden-hued chicken stew into my favorite stoneware bowl. I first created the recipe during a particularly frantic November: my husband was traveling for work, I’d just picked up a new freelance project, and our two kids had somehow synchronized their after-school activities so that every single night felt like a relay race. I needed something I could cook once, portion into glass containers, and reheat all week without anyone complaining about “leftovers again.”
One Sunday afternoon I roasted a tray of butternut squash while the chicken simmered, folded in a generous handful of spinach for color, and finished the pot with a squeeze of bright lemon. The resulting stew was everything I hoped for—protein-rich, fiber-packed, and cozy as a flannel blanket. More importantly, it tasted even better on day three after the flavors had melded. These days I make a double batch every other week; we eat it for dinner, pack it in thermoses for school lunches, and still have enough to freeze for future “I give up” nights. If you’re looking for a make-ahead meal that feels like self-care in a bowl, you’ve just found it.

Ingredients You'll Need
Great stew begins with smart shopping. Below I’ve listed the building blocks, plus the little quality cues I watch for at the market.
Chicken – I prefer boneless, skinless thighs for their higher fat content; they braise into silky morsels that don’t dry out when microwaved on day four. If you’re a die-hard breast fan, go ahead, but swap the stovetop simmer time from 25 to 15 minutes to prevent stringiness.
Winter Squash – Butternut is reliably sweet and easy to peel, though acorn, kabocha, or even sugar pumpkin work. Look for matte skins—shiny can signal underripe flesh. Shortcut: most grocery stores sell pre-cubed squash. You’ll need about four cups.
Spinach – Buy a 5-oz clamshell of baby spinach. It’s already triple-washed and wilts almost instantly, saving you a prep step. Frozen spinach is fine; thaw and squeeze out excess water or your stew will taste watery.
White Beans – Creamy cannellini beans bulk up the stew and stretch your grocery budget. If sodium is a concern, drain and rinse; you’ll wash away ~40 % of the salt.
Chicken Stock – Choose low-sodium so you control salt layer by layer. I keep a quart of homemade stock in the freezer, but a good store-bought brand (look for “chicken” rather than “stock” as the first ingredient) is perfectly acceptable.
Aromatics – A standard mirepoix of onion, carrot, and celery lays the flavor foundation. Dice small so they soften in the initial sauté and practically melt into the broth.
Tomato Paste – Buy the tube stuff if you can; you’ll use two tablespoons here and the rest won’t mold in the back of the fridge.
Lemon – Acidity brightens the earthy squash and prevents the stew from feeling heavy. Zest before juicing; the oils add an incredible perfume.
Spice Trifecta – Smoked paprika, dried thyme, and a whisper of cinnamon give the stew a subtle warmth reminiscent of Moroccan tagines without venturing into “dessert” territory.
How to Make Easy Meal-Prep Healthy Chicken Stew with Winter Squash & Spinach
Prep & season the chicken
Pat 2 lbs boneless, skinless chicken thighs dry with paper towels—moisture is the enemy of browning. Cut into 1-inch pieces, then season with 1 tsp kosher salt, ½ tsp black pepper, and 1 tsp smoked paprika. Let rest while you heat the pot.
Sear for fond
Heat 2 Tbsp olive oil in a heavy 5-qt Dutch oven over medium-high until shimmering. Add half the chicken; spread in a single layer—no stirring for 2 minutes. Flip, brown the second side, then transfer to a plate. Repeat with remaining chicken. Those caramelized bits stuck to the bottom are pure gold for flavor.
Build the aromatic base
Lower heat to medium. Add diced onion, carrot, and celery plus a pinch of salt; sauté 4 minutes until edges soften. Stir in 2 Tbsp tomato paste, 1 tsp dried thyme, ½ tsp cinnamon, and 1 bay leaf. Cook 90 seconds, stirring constantly, until paste darkens to a brick red color and smells slightly sweet.
Deglaze & simmer
Pour in ½ cup dry white wine or additional stock; scrape the pot’s bottom with a wooden spoon to release every speck of fond. Return chicken and any juices, add 3 cups diced winter squash, 2 drained cans white beans, and 3 cups low-sodium chicken stock. Bring to a gentle boil, then reduce to low, cover, and simmer 15 minutes.
Finish bright & green
Uncover, remove bay leaf, and test squash with a paring knife—it should slide through easily. Stir in 5 oz baby spinach, 1 tsp lemon zest, and 2 Tbsp fresh lemon juice. Once spinach wilts (about 60 seconds), taste for seasoning. Add more salt, pepper, or a splash of honey if your squash was particularly earthy.
Portion for meal-prep
Let stew cool 15 minutes; it will thicken slightly. Ladle into six 2-cup glass containers, dividing chicken, squash, and beans evenly. Leave a half-inch gap at the top to allow for expansion if freezing. Refrigerate up to 4 days or freeze up to 3 months.
Expert Tips
Low & Slow Wins
A gentle simmer, not a rolling boil, keeps chicken fibers from tightening into little rubber bands.
Degrease Like a Pro
If you use store-bought stock, skim fat with a spoon after refrigerating; the stew will taste cleaner on reheat.
Thaw Fast
Transfer frozen container to fridge the night before, then reheat with a splash of broth for 2 minutes in microwave.
Color Pop
Add an extra pinch of smoked paprika right before serving to revive the sunset-orange hue after freezing.
Airtight = Flavor-Safe
Press plastic wrap directly onto stew surface before snapping on lid to prevent ice crystals and off-freezer flavors.
Revive on Reheat
A quick squeeze of lemon after microwaving instantly perks up dulled flavors—taste and adjust every time.
Variations to Try
-
Moroccan Twist: Swap cinnamon for ½ tsp each ground cumin & coriander; add ¼ cup chopped dried apricots with the beans.
-
Creamy Coconut: Replace 1 cup stock with canned light coconut milk and stir in 1 Tbsp Thai red curry paste with the tomato paste.
-
Vegetarian Power: Omit chicken, double beans, and add 8 oz cubed tofu or a can of chickpeas; swap stock for vegetable broth.
-
Grains & Greens: Stir in ½ cup quick-cooking pearled barley during the last 10 minutes for a risotto-like texture.
-
Spicy Kick: Add ½ tsp red-pepper flakes with the thyme or a diced chipotle pepper for smoky heat.
Storage Tips
Refrigerator: Cool stew completely, portion into glass jars, and refrigerate up to 4 days. Glass prevents tomato-acid staining and keeps flavors true.
Freezer: Use BPA-free quart bags; lay flat to freeze, then stack like books to save space. Stew keeps 3 months at peak quality; after that it’s safe but flavors fade.
Reheat: Microwave, covered, on 70 % power for 2 minutes, stir, then 1-2 minutes more. On stovetop, warm gently with a splash of broth or water over medium-low, stirring occasionally.
Batch Doubling: Double ingredients except salt; add salt incrementally at the end. Large volumes of tomato paste can turn bitter if over-reduced.
