This keto chicken bacon ranch casserole with spinach takes three flavors everyone loves and bakes them into one creamy dish. Tender shredded chicken, crispy bacon, and tangy ranch get mixed with cream cheese and fresh spinach, then topped with melted cheddar.

It needs only about 15 minutes of prep and a handful of ingredients. The casserole bakes in 30 minutes and serves four. It is low in carbs, so it fits a keto plan, but the whole family will want a scoop.

Why This Casserole Works

Ranch does the seasoning. A cup of ranch dressing brings herbs, garlic, and tang all at once.
Cream cheese makes it rich. It blends with the ranch to coat the chicken in a thick, creamy sauce.
Bacon adds crunch and smoke. Six strips are enough to flavor every bite.
Spinach sneaks in some greens. It wilts into the sauce, so even picky eaters barely notice it.

Keeping It Keto

Chicken, bacon, spinach, and cheese have almost no carbs, so most of the carbs in this dish come from the ranch and cream cheese. Both are fairly low, which keeps each serving well within most keto plans. The main thing to watch is the dressing. Bottled ranch can range from almost zero to several grams of carbs per serving, so read the label. Homemade ranch made with sour cream, mayo, and dried herbs gives you the most control. If you are not counting carbs at all, any ranch you like will taste great here.

Ingredients and Easy Swaps

4 cups cooked, shredded chicken: Rotisserie chicken makes this very fast. Leftover grilled chicken or turkey also works.
6 strips bacon, cooked and crumbled: Cook it until crisp so it stays crunchy in the casserole. Precooked bacon bits work if you are short on time.
2 cups fresh spinach, chopped: Frozen spinach works too. Use about ½ cup thawed and squeeze it very dry.
1 cup ranch dressing: Check the label for added sugar if you are strict keto. You can also mix a packet of dry ranch seasoning with ¾ cup sour cream and ¼ cup mayo.
½ cup softened cream cheese: Full-fat works best. Let it come to room temperature so it mixes in smoothly.
1 cup shredded cheddar: Colby jack, pepper jack, or mozzarella are all good swaps.
1 teaspoon each garlic powder and onion powder, salt and pepper: Go light on salt since bacon and ranch are salty.

How to Make It at a Glance

Heat the oven to 350°F and grease a baking dish. An 8×8 or 11×7 inch dish works well.
In a large bowl, mix the chicken, bacon, spinach, ranch, cream cheese, garlic powder, onion powder, salt, and pepper until combined.
Spread the mixture evenly in the dish and sprinkle the cheddar on top.
Bake for 25 to 30 minutes, until the cheese is melted and bubbly and the center is hot.
Let it cool for a few minutes before serving.

Common Mistakes to Avoid

Soggy bacon. Undercooked bacon gets chewy in the sauce. Cook it until fully crisp, and save a little to sprinkle on top.
Wet spinach. Frozen spinach holds a lot of water. Squeeze it dry or the casserole will be runny.
Lumpy sauce. Cold cream cheese will not mix in. Soften it first or microwave it for 15 seconds.
Serving it too hot. A short rest helps the sauce thicken so it scoops neatly.

Variations

Add broccoli: Stir in 2 cups of small steamed broccoli florets for more veggies.
Cauliflower rice base: Mix in 2 cups of cauliflower rice to stretch it to more servings.
Buffalo ranch: Add 2 to 3 tablespoons of hot sauce for a spicy kick.
Jalapeño popper style: Stir in diced pickled jalapeños and top with extra bacon.

What to Serve With It

A crisp side salad with cucumbers and a simple vinaigrette is the easiest pairing. Roasted green beans, garlic butter mushrooms, or steamed broccoli also keep the meal low carb. Celery and cucumber sticks are a fresh, crunchy side that kids like to dip in extra ranch. For anyone not eating keto, warm dinner rolls are a good addition.

Make Ahead, Storage, and Reheating

Make ahead: Cook the bacon and shred the chicken up to 2 days ahead. You can also assemble the whole casserole, cover it, and chill it for up to 1 day. Add about 10 minutes to the bake time.

Storage: Keep leftovers in an airtight container in the fridge for 3 to 4 days. Freezing is possible for up to 2 months, but the cream cheese sauce may separate a bit.

Reheating: Microwave single portions for 1 to 2 minutes, or cover the dish with foil and bake at 350°F until it reaches 165°F in the center.

FAQ

Is ranch dressing keto?
Most full-fat ranch dressings are low in carbs. Check the label, since some brands add sugar.

Can I use raw chicken?
Cook it first. Bake, poach, or sauté the chicken until it reaches 165°F, then shred it before mixing.

Can I double it?
Yes. Double everything and bake in a 9×13 inch dish for 35 to 40 minutes.

Can I bake the bacon instead of frying it?
Yes. Lay the strips on a foil-lined sheet pan and bake at 400°F for 15 to 20 minutes until crisp. Cleanup is much easier.

Keep cooked chicken and bacon in the fridge, and this casserole is one of the quickest dinners you can make. The full recipe card is below.
