Ingredient Guide
When putting together your Keto Greek Chicken Casserole Recipe, choosing the right ingredients can make a big difference in flavor and texture. Let’s walk through each key component so you know exactly what to look for and how to prep it for the best results.
- Chicken: Use cooked chicken—rotisserie is a great shortcut! If you cook it yourself, shred or dice it finely for even mixing.
- Cherry tomatoes: Fresh and ripe will bring juicy bursts. Halve them so their sweetness complements the creamy sauce.
- Black olives: Choose pitted Kalamata for authentic flavor; slice them to evenly distribute their salty bite.
- Feta cheese: Crumbled feta adds tang and creaminess. Get a good-quality block for better melting and taste.
- Heavy cream: This is crucial to create that rich, luscious sauce that holds the casserole together.
- Herbs & spices: Dried oregano and garlic powder are classic and straightforward; fresh herbs can also boost brightness if you have them.
- Salt & pepper: Essential to season everything evenly; don’t be shy here because feta and olives are already salty.
- Olive oil: Just a little to grease your dish and enhance the Mediterranean vibe.

How to Make Keto Greek Chicken Casserole Recipe
Step 1 — Prep & Ready
Start by preheating your oven to 375°F (190°C) — this ensures it’s hot enough for a bubbly, golden finish. While the oven warms, shred or dice your cooked chicken evenly so every forkful has a perfect mix of ingredients. Halve the cherry tomatoes to release their sweet juices as they bake. Slice the olives thinly to spread their robust flavor without overpowering the casserole. Don’t forget to lightly grease your baking dish with olive oil to prevent sticking and add subtle richness.
Step 2 — Cook with Confidence
In a large bowl, toss together your chicken, tomatoes, olives, and crumbled feta. Then pour in the heavy cream along with dried oregano, garlic powder, salt, and pepper. Mix everything gently but thoroughly — you want ingredients evenly coated in the creamy sauce. Transfer this mixture to your prepared baking dish and pop it in the oven. Bake for about 25-30 minutes until the casserole is hot and bubbling. You’ll notice the edges begin to brown slightly and the aroma fills your kitchen with that inviting Mediterranean warmth.
Step 3 — Finish & Serve
Once out of the oven, let your Keto Greek Chicken Casserole rest for 5-10 minutes—this helps the sauce thicken and settle. You’ll see a creamy, slightly golden top with crispy edges tempting you to dig in. Taste and adjust with a little extra salt or pepper if needed. For a fresh lift, sprinkle chopped fresh parsley or dill on top before serving. This casserole pairs wonderfully with a crisp green salad or sautéed low-carb veggies for a complete, satisfying meal.
Extra Helpful Tips
I’ve found these small tweaks really boost your success with this Keto Greek Chicken Casserole Recipe, making each bake better than the last.
- Watch for This Sign: When the casserole edges are bubbling and slightly golden, it’s the perfect time to take it out—you don’t want to overbake and dry it.
- Temperature Trick: Let the casserole come to room temperature before baking if your chicken is chilled; this helps it heat evenly and makes the cream sauce silkier.
- Prep-Ahead Option: Mix all the ingredients and assemble it in your baking dish the night before. Just cover and refrigerate—bake fresh when ready.
- Avoid This Common Mistake: Don’t skip greasing your baking dish—olive oil prevents sticking and adds a subtle flavor accent that rounds out the dish.
Serve & Enjoy
Easy Enhancements
You can easily elevate your Keto Greek Chicken Casserole Recipe with a few simple additions. A handful of chopped fresh herbs like oregano, dill, or parsley sprinkled on top adds bright color and fresh flavor. If you like a little heat, red pepper flakes or a drizzle of spicy olive oil after baking amps it up nicely. For extra creaminess, a spoonful of Greek yogurt on the side complements the tangy feta perfectly.
Tasty Pairings
This casserole pairs beautifully with crisp, refreshing sides like a Greek cucumber salad or roasted asparagus for a low-carb balance. If you’re serving a group, a simple cauliflower rice pilaf or garlic sautéed green beans blends seamlessly alongside. To sip, a dry white wine or sparkling water with lemon will brighten the feast without overpowering these Mediterranean flavors.
Quick Plating Tips
Keep plating simple but elegant: scoop a generous portion onto a warm plate, then garnish with a few extra olives and a sprig of fresh herb. A wedge of lemon on the side encourages guests to add a zingy brightness if they like. Using a colorful plate can make the creamy, golden casserole pop visually, making your meal feel even more inviting.
Store, Freeze & Reheat
Fridge Storage
Your Keto Greek Chicken Casserole will stay fresh in an airtight container in the fridge for up to 3-4 days. You might notice the creamy sauce thickens as it chills, but don’t worry—this just means it’s ready to be reheated gently for that comforting texture all over again.
Freezer Friendly?
This casserole freezes well, making it great for meal prep. Freeze individual portions or the whole dish in a freezer-safe container for up to 3 months. When thawing, do it slowly overnight in the fridge to avoid the sauce turning watery. Reheat gently to lock in that creamy consistency.
Reheat Like New
For reheating, the oven is your best friend—warm at 325°F (160°C) until heated through (about 15-20 minutes), which restores the casserole’s creamy texture and crispy edges. Microwave reheats faster but do it in short bursts, stirring if possible, to avoid drying out. A skillet on low heat with a splash of water or broth also revives moisture beautifully.
Keto Greek Chicken Casserole Recipe FAQs
Absolutely! Just thaw your chicken fully and pat it dry before mixing it with the other ingredients to avoid excess moisture in the casserole.
Full-fat coconut milk works as a dairy-free alternative, though it will add a subtle coconut flavor. Alternatively, you can use cream cheese thinned with a splash of broth or milk.
