• Reduced-fat cream cheese (4 oz, softened)
• Ranch seasoning (1 packet or 2 tablespoons)

Method

 

1. Prep the oven and pan: Heat the oven to 375°F (190°C). Lightly grease a 9x13-inch baking dish.
2. Cook the aromatics: Warm olive oil in a skillet over medium heat. Add celery and garlic, and cook 3–4 minutes until fragrant and slightly softened.
3. Make the buffalo sauce base: In a large bowl, whisk cream cheese, Greek yogurt, cottage cheese, ranch seasoning, and 3/4 cup buffalo hot sauce until smooth. If you like it extra spicy, add more hot sauce to taste.

5. Add the cheese: Mix in half the mozzarella and half the cheddar. The rest goes on top.

Keeping It Fresh

• Storage: Cool completely, then cover and refrigerate for up to 4 days. It holds moisture well thanks to the yogurt and cheese blend.
• Reheating: Microwave individual portions 1–2 minutes, or cover the whole dish with foil and warm at 325°F (165°C) for 15–20 minutes.
• Freezing: Freeze tightly wrapped portions for up to 2 months. Thaw overnight in the fridge, then reheat.

  If using cauliflower rice, expect a little extra moisture—just blot if needed.

• Meal prep tip: Portion into single-serve containers with a side of crunchy celery sticks for texture contrast.

Health Benefits

• High-quality protein: Chicken breast, Greek yogurt, and cottage cheese deliver a strong protein punch to support muscle repair and keep you full longer.
• Lighter creamy base: Swapping most of the mayo with Greek yogurt and cottage cheese cuts saturated fat while keeping the creamy texture.
• Micronutrient boost: Celery and green onions add fiber and antioxidants, and using cauliflower rice increases fiber while lowering overall calories.
• Customizable macros: Choose cauliflower rice for lower carbs or brown rice for sustained energy and extra fiber.

What Not to Do

• Don’t skip draining cauliflower rice: Excess moisture can make the casserole watery. Squeeze thawed cauliflower rice in a clean towel.
• Don’t overbake: Overcooking can dry out the chicken and make the dairy separate. Pull it when the cheese is melted and edges bubble.
• Don’t use only cream cheese: The combo of yogurt and cottage cheese keeps protein high and texture light.

  All cream cheese makes it heavy and lower in protein.

• Don’t forget to rest: A short rest helps everything set, so slices hold together and flavors meld.

Recipe Variations

• Extra-veggie version: Add diced bell peppers or shredded carrots with the celery. Sauté first to keep moisture in check.
• Ranch-forward: Stir in 2 tablespoons of chopped fresh dill and parsley. Use a bit less hot sauce and a little more ranch seasoning.
• Blue cheese lover’s: Mix 1/2 cup crumbles into the casserole and add more on top after baking.
• Low-carb, extra protein: Stick with cauliflower rice and add an extra 1/2 cup cottage cheese.

  Keep an eye on moisture and bake uncovered.

• Gluten-free: Most ingredients are naturally gluten-free. Just confirm your ranch seasoning and hot sauce are labeled GF.
• Spice control: Use 1/2 cup hot sauce for mild, 3/4 cup for medium, 1 cup for hot. A squeeze of honey can soften the heat without losing the buffalo flavor.
• Rotisserie shortcut: Shred a store-bought rotisserie chicken to save time.

  Use mostly breast meat for leaner macros.

FAQ

Can I use canned chicken?

Yes. Drain it well and use about 3–4 cans (12–16 ounces total drained weight). The texture is softer, but the flavors still work.

Add a little extra shredded cheese to improve structure.

What’s the best hot sauce for buffalo flavor?

A classic cayenne-based hot sauce like Frank’s RedHot gives the most familiar buffalo taste. You can use your favorite brand, but avoid thick, sweet wing sauces if you want that clean, tangy heat.

Can I make this dairy-free?

You can try dairy-free cream cheese, plain dairy-free yogurt, and vegan shredded cheese. Flavor will be close, but protein will drop unless you add a plant protein like shredded seasoned chick’n.

Adjust salt and hot sauce to taste.

How do I keep it from getting watery?

Squeeze moisture from thawed cauliflower rice, sauté watery veggies first, and let the casserole rest before slicing. If using frozen chicken, make sure it’s fully thawed and patted dry.

Is this good for meal prep?

Absolutely. It stores well for 4 days and reheats without getting rubbery.

Portion into containers and add fresh toppings after heating for best texture.

Can I make it ahead?

Yes. Assemble up to 24 hours in advance, cover, and refrigerate. Add 5–10 minutes to the bake time since it will be cold going into the oven.
