Crock Pot Chicken and Wild Rice Casserole

Enjoy this creamy, hearty slow-cooker casserole built on nutty wild rice, tender chicken, and everyday vegetables. It’s weeknight-reliable, hands-off for most of the cook, and easy to adapt for different eaters at the table.

Wild rice holds its texture better than white rice in a slow cooker. That’s the backbone of this dish: grains that stay pleasantly chewy instead of turning pasty. From there, the flavor is simple on purpose—garlic, thyme, and a few pantry spices—so it plays nicely with whatever you like to add: mushrooms, broccoli, spinach, or a handful of frozen peas at the end for color. The creaminess comes together without canned soup. A quick cornstarch-and-evaporated-milk finish keeps the sauce silky and stable, even after a night in the fridge.

If you’re cooking for a busy evening, the method fits how real life looks. Dice a few vegetables, rinse the rice, season the chicken, and let the slow cooker do the rest. You won’t sear, dirty extra pans, or babysit a simmer. The rice cooks first in broth so it keeps its bite. The chicken goes in partway through to avoid drying out, and the vegetables soften in the last stretch so they don’t fade into the background. A grated Parmesan finish adds depth without heaviness, and a squeeze of lemon wakes the whole pot up.

This recipe also respects timing realities. On low, it’s about five to six hours total; on high, roughly three to four. The pot will wait on warm for you for a bit if traffic or practice runs long. Leftovers reheat well, and the casserole freezes cleanly if you want to stock a few individual portions for lunches.

Under the hood, it’s a balanced meal: lean protein, whole grains, and plenty of vegetables. Wild rice is naturally gluten-free and higher in protein and fiber than most rices. Boneless thighs are forgiving and juicy, but breasts work, too, if you watch temperature. If you prefer dairy-free, you can finish the pot with unsweetened oat milk or coconut milk plus the cornstarch slurry; the texture stays creamy and the seasoning still shines.

Below you’ll find detailed equipment, timing, a dual-unit ingredient table, step-by-step instructions, and nutritional information. After the main recipe, there are variations, swaps, make-ahead directions, and troubleshooting notes so you can dial this in for your kitchen, your slow cooker, and your crew.

Step-by-Step Instructions

1) Start the Rice and Broth

1. Rinse the wild rice under cold water until the water runs mostly clear.
2. Add the rinsed wild rice to the slow cooker with the chicken broth, olive oil, ½ tsp kosher salt, black pepper, garlic, onion, carrots, celery, thyme, paprika, and bay leaves.
3. Cover and cook: Low for 2½ hours (or High for about 1½ hours). The rice should be just past al dente but still firm; it will finish later.

2) Add the Chicken

4. Season the chicken pieces with the remaining ¾ tsp kosher salt.
5. Stir the pot, then nestle the chicken evenly into the rice and broth.
6. Cook covered: Low for 2 to 2½ hours (or High for 1 to 1¼ hours), until the chicken is tender and reaches 165°F / 74°C.

3) Finish the Sauce and Vegetables

7. Whisk evaporated milk and cornstarch in a small bowl until smooth.
8. Stir in mushrooms (if using) and frozen peas (or broccoli).
9. Pour in the slurry, stir well, and cook covered on High for 15–20 minutes, stirring once, until the sauce thickens and the vegetables are bright and just tender.

4) Season and Serve

10. Remove bay leaves.
11. Stir in Parmesan and lemon juice. Taste; add salt or pepper as needed.
12. Sprinkle with parsley and ladle into warm bowls.

Texture targets: The rice should be tender-chewy, the sauce glossy and spoonable—not soupy—and the chicken juicy. If it’s too thick, whisk in hot broth or water a splash at a time. If it’s too loose, leave the lid slightly ajar on High for 10–15 minutes to reduce, or add 1 more tsp cornstarch whisked with 1 Tbsp cold water and simmer 5 minutes.

Why This Method Works

Wild Rice First

True wild rice is resilient. Giving it a head start in broth lets the grains hydrate without oversoftening. White-rice blends tend to disintegrate in slow cookers; pure wild rice keeps structure and a nutty bite.

Chicken Second

Adding chicken later prevents stringy meat. The pieces gently poach in starchy, aromatic broth and stay juicy. Thighs are more forgiving; breasts are fine if you monitor temperature closely.

Dairy-Free Thickening

A cornstarch slurry set with evaporated milk (or a dairy-free alternative) delivers creaminess without canned soup. It won’t break when reheated and keeps the sauce smooth.

Bright Finish

Lemon and Parmesan add acidity and umami, balancing the richness and rounding out the wild rice’s earthy notes.

Ingredient Notes & Smart Swaps

• Chicken: Boneless, skinless thighs are ideal. If using breasts, cut into 1-inch pieces and start checking for 165°F (74°C) at the early end of the range.
• Broth: Low-sodium gives you control over seasoning. Vegetable broth works if you’re cooking for a mixed crowd.
• Vegetables: Mushrooms boost savoriness; peas add color and sweetness; broccoli brings crunch if added at the end. Stir in baby spinach in the last 5 minutes if you want greens.
• Herbs & spices: Thyme is classic, but rosemary or a pinch of poultry seasoning works. Smoked paprika turns the flavor a shade earthier.
• Creaminess options: Evaporated milk is stable. Whole milk, half-and-half, or unsweetened oat or coconut milk also work with the slurry. Avoid heavy cream here; it can feel cloying.
• Cheese: Parmesan melts in and seasons the sauce. For dairy-free, skip it and add 1–2 tsp white miso or nutritional yeast at the end for depth.
• Rice type: Use 100% wild rice (Zizania). If you only have a wild-rice blend, shorten the initial rice cook by 30–45 minutes and begin checking often; blends soften faster.

Make-Ahead, Storage, and Reheating

• Prep ahead (24 hours): Rinse rice; dice vegetables; cut chicken. Refrigerate in separate containers.
• Cook-ahead: Complete the recipe. Cool quickly, uncovered, then refrigerate up to 4 days.
• Freeze: Portion into airtight containers (leave a little headspace). Freeze up to 3 months. Thaw overnight in the fridge.
• Reheat: Add a splash of broth or water and warm gently on the stovetop over medium-low heat or in the microwave at 60–70% power, stirring occasionally, until hot.
• Food safety: Reheat leftovers to 165°F / 74°C. Don’t leave cooked casserole at room temperature for more than 2 hours.

Troubleshooting

• Rice is too firm: Stir in ¼–½ cup (60–120 ml) hot broth or water, cover, and cook on High 10–15 minutes.
• Rice is too soft: Next time, shorten the first rice stage by 15–20 minutes or switch to 100% wild rice if you used a blend.
• Sauce too thin: Simmer on High with the lid ajar 10–15 minutes, or add 1 tsp cornstarch whisked into 2 tsp cold water; simmer 5 minutes.
• Sauce too thick: Whisk in hot broth, a few tablespoons at a time, to loosen.
• Flat flavor: Add a pinch of salt and a few drops more lemon. Parmesan also sharpens the finish.
• Chicken a bit dry: Use thighs next time, add chicken a little later, and verify your cooker isn’t running hot.

Variations

• Chicken & Broccoli Bake-Style: Replace peas with 2 cups (200 g) small broccoli florets. Stir in during the slurry step and cook until bright and crisp-tender.
• Mushroom Lover’s: Double the mushrooms and add 1 tsp soy sauce or tamari with the slurry for extra savoriness.
• Herb Garden: Swap thyme for 1 Tbsp fresh rosemary and ¼ cup chopped parsley; finish with lemon zest.
• Southwest Twist: Add 1 tsp ground cumin, ½ tsp chili powder, and substitute corn for peas; finish with cilantro and a little Monterey Jack instead of Parmesan.
• Turkey Leftovers: Stir in 3 cups (360 g) diced cooked turkey during the slurry step; heat through 10 minutes.

Serving Ideas

• Spoon into bowls and top with extra Parmesan and parsley.
• Add a crisp, simple side salad (greens, lemon, olive oil, salt, pepper).
• Warm crusty bread or buttered toast points for the table.
• For a higher-veg plate, fold in a few handfuls of baby spinach in the last 5 minutes.

Frequently Asked Questions

Can I use a wild-rice blend?
Yes, but blends cook faster and can soften too much. Shorten the first rice stage by 30–45 minutes and watch closely.

Can I start with frozen chicken?
No. For food safety and even cooking, thaw chicken fully in the refrigerator before adding it to the slow cooker.

Can I skip the cornstarch?
You’ll lose body in the sauce. If you prefer not to use cornstarch, whisk 1 Tbsp flour (8 g) into the milk and simmer longer, or reduce the broth by ½ cup (120 ml).

Can I cook it fully on High?
Yes. Expect roughly 3 to 4 hours total: 1½ hours for rice-and-broth, 1 to 1¼ hours after adding chicken, plus 15–20 minutes to thicken.

How do I scale for a crowd?
Use an 8-quart cooker and increase all ingredients by 50%. Add 10–15 minutes to each stage; check rice and chicken for doneness rather than relying only on time.
