Storage and Reheating Tips

If you have leftovers, store the chicken and sauce in an airtight container in the refrigerator for up to 3 days. To reheat, place the chicken in a covered dish in the oven at 350°F for about 15 minutes or until warmed through, or microwave it in individual portions. You can also freeze the chicken and sauce for up to 3 months. Thaw overnight in the fridge before reheating.

Fun Fact: Portobello Mushrooms – The "Steak" of the Mushroom World

Portobello mushrooms are often referred to as the "steak" of the mushroom world due to their meaty texture and rich, umami flavor. They’re perfect for adding depth and richness to dishes, which is why they shine in this creamy chicken recipe. The portobellos not only add great flavor but also a hearty texture that pairs wonderfully with the tender chicken.

Cooking Tips

• Marinate for Maximum Flavor: Letting the chicken marinate for at least 2 hours allows the herbs and seasoning to really penetrate the meat, giving it incredible flavor.
• Thicken the Sauce: Adding the cornstarch mixture at the end ensures that the sauce is thick and creamy without being too runny.
• Keep the Chicken Whole: When serving, use a spatula to carefully remove the chicken breasts so they remain intact for a beautiful presentation.

Optional Variations

• Add Vegetables: For a more well-rounded meal, add some chopped carrots or baby potatoes to the slow cooker along with the chicken.
• Cheese Swap: If you’re not a fan of pepper jack cheese, you can swap it for mozzarella, provolone, or even Swiss cheese for a different flavor profile.
• Garlicky Goodness: Add extra garlic to the sauce for a more intense garlic flavor if you’re a garlic lover.
