Tips for success

For the best texture, serve this dish as soon as it's done. The sauce will thicken as it cools, so if you're not ready to eat, keep the slow cooker on warm.

If you prefer a thinner sauce, stir in a splash of chicken broth or milk before serving. To make the dish even more substantial, serve it over cooked penne, rice, or mashed potatoes. The creamy sauce is perfect for soaking into carbs.

To keep the asparagus from overcooking, place it on top of the chicken rather than at the bottom of the slow cooker. You can also cut the asparagus into smaller pieces if you prefer.

If you want a bit of heat, add a pinch of red pepper flakes when layering the ingredients. This recipe is a great base for customization, so feel free to experiment with different cheeses or add a handful of spinach during the last 30 minutes of cooking.

Variations

Add Mushrooms: Add 8 oz sliced mushrooms along with the asparagus for an earthy flavor. Sauté them briefly in butter before adding to the slow cooker to deepen their taste.
Use Chicken Thighs: Swap chicken tenderloins for boneless, skinless chicken thighs. Cook on low for 5 hours for extra juicy, tender meat. The sauce will be even richer.
Make it Spicy: Add 1/2 teaspoon red pepper flakes or a diced jalapeño when layering the ingredients. The heat balances the creamy sauce nicely.
Add Bacon: Crumble 4 slices of cooked bacon over the top before serving for a smoky, salty crunch. This adds a new layer of flavor without changing the cooking process.

Storage and make-ahead

Fridge: Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat gently with a splash of broth or milk to restore the creamy texture.
Freezer: Freeze in an airtight container for up to 2 months. Thaw overnight in the refrigerator before reheating.
Reheat: Reheat in the microwave or on the stovetop over low heat, adding a splash of milk or broth to loosen the sauce. Stir occasionally until heated through.

Store leftovers in an airtight container in the refrigerator for up to 3 days. The sauce will thicken as it cools; when reheating, add a splash of chicken broth or milk to loosen it. Reheat gently in the microwave or on the stovetop until warmed through. The chicken may become slightly drier upon reheating, so be careful not to overheat.

This recipe can be prepped ahead by layering all the ingredients in the slow cooker insert and storing it in the refrigerator overnight. In the morning, place the insert in the slow cooker and cook as directed.

You may need to add 30 minutes to the cooking time because the ingredients start cold. Alternatively, you can cook the dish fully and refrigerate it, then reheat gently before serving.

Serving ideas

Serve this golden mozzarella chicken over a bed of al dente pasta, such as penne or fettuccine, to catch every bit of the creamy sauce. The pasta soaks up the garlicky cheese sauce and makes the meal more filling.

A side of crusty bread is also great for sopping up the extra sauce. For a lighter option, serve it with steamed rice or quinoa. The dish is hearty enough to stand on its own, but the sauce is so good you'll want something to dip into it.

Garnish with a sprinkle of fresh parsley or cracked black pepper for a pop of color and freshness. This dish pairs well with a simple green salad or roasted vegetables. If you're serving a crowd, set up a buffet with the chicken, pasta, and a bowl of extra sauce. The leftovers are just as delicious the next day, making this a great make-ahead meal for busy weeks.

Frequently asked questions

Can this recipe be made with frozen chicken tenders?

Yes, but the cooking time will be longer, and the texture may be less tender. It is safer to thaw the chicken in the refrigerator overnight before adding to the slow cooker. If using frozen chicken, cook on low for 5 to 6 hours and always check that the internal temperature reaches 165°F (74°C).

Why is the sauce thin after cooking?

The sauce may be thin if the slow cooker is too hot or if the lid is lifted frequently, allowing condensation to drip back in. To thicken it, leave the lid off for 10 to 15 minutes on the warm setting. You can also stir in a slurry of 1 tablespoon cornstarch and 2 tablespoons cold water, then cook for a few more minutes.

Can the asparagus be swapped for another vegetable?

Absolutely. Broccoli florets, green beans, or zucchini slices work well. Adjust the cooking time based on the vegetable's tenderness. Add heartier vegetables like broccoli at the start, and more delicate ones like zucchini in the last hour of cooking.

How can this recipe be made gluten-free?

Use a gluten-free condensed cream of celery soup or make a homemade version with a gluten-free flour blend. Ensure all other ingredients, including the garlic herb butter and mozzarella, are certified gluten-free if needed. The rest of the recipe remains the same.

What is the best way to reheat leftovers?

Reheat gently to avoid drying out the chicken. Add a splash of chicken broth or milk to the sauce and warm in a saucepan over low heat, stirring occasionally. Alternatively, microwave in 30-second increments, stirring in between, until heated through. Avoid boiling, which can make the chicken tough.

Crockpot Chicken Tenders with Asparagus and Mozzarella

Prep 10 minCook 4 hTotal 4 h 10 minServes 4

Ingredients

1 1/2 lb chicken breast tenderloins
1 lb fresh asparagus spears, trimmed
1 can (10.5 oz) condensed cream of celery soup
2 cups shredded whole-milk mozzarella cheese
2 tbsp garlic herb butter, cut into pats

Instructions

Place the chicken breast tenderloins in a single layer in the bottom of the slow cooker. Scatter the trimmed asparagus spears evenly over the chicken. Spoon the condensed cream of celery soup over the top, spreading it gently to cover the chicken and asparagus as much as possible.
Sprinkle the shredded mozzarella cheese evenly over the soup. Place the pats of garlic herb butter on top of the cheese. Do not stir; simply leave the ingredients layered as they are.
Cover the slow cooker and cook on low for 4 hours, or until the chicken is fork-tender and cooked through. Do not lift the lid during the first 3 hours to keep the heat steady. The sauce will bubble gently around the edges.
After 4 hours, check the internal temperature of the chicken with an instant-read thermometer. It should read at least 165°F (74°C) in the thickest part of the tenderloins. If not, continue cooking in 15-minute increments until it reaches the safe temperature.
Gently stir the sauce to combine the melted cheese and soup into a creamy sauce. Spoon the chicken and asparagus over cooked pasta or serve as is. The sauce should be thick and stretchy, coating the chicken and vegetables.
