The Low‑Carb Casserole That Feels Like Home

I made this while the dog barked at a squirrel and my kid spilled juice on the math homework — and suddenly dinner was the hero. This Bariatric Low Carb Chicken Enchilada Casserole is the kind of thing that fixes a chaotic evening: quick, cheesy, and UNREAL comforting. It’s low-carb but not sad; it’s bariatric-friendly without being clinical. I love that it’s basically dump-and-bake so you can get the chaos under control and still sit down to something SO GOOD. If you’re into creamy bakes, you might also like my take on a creamy low-carb chicken casserole that plays in the same league.

Hey, I’m Jason. I grew up in Canton, Ohio, where food is how we take care of each other. I learned to cook standing on a chair next to my mom, watching her turn butter and garlic into something that made the whole house smell like comfort. I started The Only Recipe because I was tired of meals that looked good online but flopped in real life. Around here, it’s all about food that works, tastes good, and brings people together. If you’re craving meals that feel like home and smell like a warm hug, you’re in the right place.

Ingredients Needed

Here’s what you’ll pull together—grouped like a pro so you don’t overcomplicate things.

Base

• 12 oz cooked chicken, cubed or shredded (about 1 lb raw; rotisserie is perfect)
• 1 1/2 cups enchilada sauce (pick a mild or medium, whatever your family digs)

Mix-ins & flavor

• 4 oz diced green chiles (adds gentle heat and tang)
• 1/4 cup cilantro, chopped (optional but freshens the whole dish)

Cheese & topping

• 1 1/2 cups shredded Mexican cheese blend, divided (use part inside, part for top)
• Greek yogurt for garnish (optional — creamy, tangy swap for sour cream)

How to Make This Recipe?

Step 1 — Preheat and prep

Preheat your oven to 375°F. Get an 8×8 casserole dish out and spray or rub lightly with oil so nothing sticks. Preheating means your cheese melts evenly and you’re not waiting by the oven — little wins.

Step 2 — Mix the filling

In a large bowl, toss together the cooked chicken, enchilada sauce, half of the shredded cheese, chopped cilantro, and diced green chiles. You want everything evenly coated — the sauce should cling to the chicken, not puddle in the bowl. This is where the flavor comes alive.

Step 3 — Assemble and bake

Spoon the mixture into the prepared 8×8 dish, spreading it so the top is even. Sprinkle the remaining cheese over the top. Pop it into the preheated oven and bake for about 15 minutes, or until it’s heated through and the cheese is melted and a little bubbly. Look for golden edges and that irresistible cheese stretch.

Step 4 — Finish and serve

Let it rest a couple minutes out of the oven. Garnish with extra chopped cilantro and a dollop of Greek yogurt if you want that tang and creaminess. Scoop generous portions and enjoy. This Bariatric Low Carb Chicken Enchilada Casserole should be warm, melty, and comforting — not dry.

How to Store It

• Fridge: Cool completely, cover tightly, and refrigerate up to 4 days. Reheat in a 325°F oven until warmed through, or microwave single servings.
• Freezer: Portion into airtight containers and freeze up to 3 months. Thaw overnight in the fridge, then reheat in the oven for best texture.
• Reheating tip: If reheating from frozen, cover with foil for the first part of baking so cheese doesn’t burn; uncover to refresh the top.

Expert Tips (Jason-approved)

• Use rotisserie chicken to save time and boost flavor — I do it on busy nights.
• Want it saucier? Stir an extra 1/4 cup enchilada sauce into the mix before baking.
• Cheese swap: Monterey Jack blends beautifully, or use pepper jack for a spicier kick.
• Add veggies: Fold in a handful of sautéed onions, bell peppers, or spinach for more bulk without many carbs.
• Portion control for bariatric needs: Serve in small ramekins; the melty cheese makes small portions feel indulgent.
