☑️ Storage Instructions

Fridge: Store any leftovers in an airtight container in the fridge for up to 3 days.

Freezer: It also freezer beautifully which makes an easy solution for busy weeknight meal ideas. Just store leftovers in an airtight freezer safe container for up to a couple of months. You can even divide it into portions before freezing. Be sure to date the outside of the container so you’ll know the date it was frozen.

💡 Tips

• Baking Bacon in the Oven on a Rack means no stovetop splatter to clean up!
• Make your own dressing mix. Premixed ranch dressing mixes usually have maltodextrin or sugar that’s not recommended for those on Keto or low carb diets.
• Drain the spinach well by pressing out extra liquid with paper towels.
• For the best flavor, cook the bacon until crispy before crumbling.
• Shred your own cheddar instead of buying pre-shredded for a smoother melt.

🍴 What to Serve with Ranch Chicken Casserole

Since this Keto casserole is rich in flavor and healthy fats, a simple side salad would be the most suitable pairing. Greek Salad, Classic Wedge Salad, Mediterranean Cucumber Salad or this Strawberry Spinach Salad are all great options.

🔄 Substitutions and Additions

• Chicken: There are several options for how to prepare chicken for this recipe. You can boil your own or even buy rotisserie chicken, just be sure to look for any added sugar or preservatives in grocery store rotisserie chicken.
• Spinach: You can use fresh spinach if you prefer. One pound fresh spinach is the equivalent of 9 ounces of frozen.
• Cheese: Cheddar cheese provides a great contrast to the creaminess of the cream cheese. But if you have another cheese that’s your favorite, it will work fine. You’ll want a good melting cheese to use in its place.
• Veggies: Swap spinach for broccoli florets if you want a different veggie. Or Add diced jalapeños or green chiles for a little heat.
• Cream cheese: Cream cheese gives this Keto casserole the classic tangy ranch flavor, but if you’d like a more subtle flavor, opt for Mascarpone cheese. It has a milder flavor and less carbs than cream cheese.

Is Chicken Casserole Keto?

This one certainly is. It has a lot of healthy fat from the cream cheese and bacon balanced with the right amount of protein from the chicken and is loaded with vitamins and minerals with the added spinach.

Can I Make This Ahead of Time?

Yes, assemble the casserole, cover, and refrigerate. Bake within 24 hours.

Why is My Casserole Watery?

It usually means the spinach wasn’t drained well. Press out as much liquid as possible before mixing it in.

Can I Use Fresh Spinach Instead of Frozen?

Yes, just sauté it first to cook down and release moisture.
