Tips From My Kitchen

We made the potatoes in the Air Fryer beforehand so they added a crisp and a delicious herb flavor from the seasoned dill. 

Feel free to get creative with veggies! Consider adding sautéed mushrooms, spinach, bell peppers, zucchini, or roasted garlic—either cooked alongside the chicken or mixed into the casserole before baking.

Benefits of an Air Fryer

Our household uses the Air Fryer 3-4x per week. I love that it adds an extra crisp to meals without all of the extra calories and it doesn't involve frying. It's a very light way to make a meal more flavorful and crispy.

Who Inspired This Recipe

This recipe was inspired by Cook it With Tim, but I made a few changes to suit our family’s taste. I love making these small adjustments! I never add salt in our recipes. Kevin has chronic kidney disease and high blood pressure so I typically omit the salt when possible.

I added a dill weed seasoning and smoked paprika in our potatoes. We are currently out of olive oil and vegetable oil so I used PAM cooking spray as the oil. Instead of using oils like vegetable or olive oil, I found that PAM cooking spray works really well in the air fryer, giving the potatoes a perfect crisp without adding extra calories or fat.

For the chicken we didn't use minced garlic and I replaced Garlic Parmesan Sauce with Garlic Alfredo Sauce. If you like spice, you can add red pepper flakes or cayenne pepper.

• 1 tsp garlic powder
• 1 tsp onion powder
• 1 tsp smoked paprika

Notes: The dill weed seasoning and smoked paprika are optional but highly recommended for added flavor and aroma!

✓ Step #10: Prepare the casserole – In a baking dish, add chicken and sauce, top with air-fried potatoes and shredded mozzarella, then bake at 375°F for 15 minutes or until cheese is melted.

Keep It Fresh: Storage Tips

Store leftovers in an airtight container in the fridge for up to 3 days. For the best results when reheating leftovers, microwave for 2 minutes or until warm. You can also pop it in the oven at 350°F for about 10 minutes to get that crispy texture back.

Freezing Tip

After assembling the casserole (before baking), allow it to cool. Then wrap tightly in plastic wrap or aluminum foil, place it in an airtight or freezer-safe container, and store for up to 2 months. To avoid mushy potatoes, undercook them by about 10 minutes before assembling.

This homemade hamburger helper combined creamy cheese, with tender pasta, and had great seasoning choices which included onion powder, garlic powder, and chili powder for a little kick. It was flavorful, and really good, with Jace and I both rating it an 8/10 and wanting to make it again. Skip the box!
