Ingredients Equipment Method Notes

Ingredients

  

• 2 cups cooked chicken, shredded (rotisserie recommended)
• 3 medium zucchinis, sliced into half-moons
• 1.5 cups shredded cheddar cheese (or Mexican blend)
• 0.5 cup heavy cream
• 1 tsp garlic powder
• salt and pepper, to taste

Equipment

• oven
• baking dish
• knife for slicing zucchini
• mixing bowl (optional)
• measuring cups and spoons

Method

 

1. Preheat your oven to 375°F. This isn’t a suggestion—cold ovens lead to sad casseroles.
2. Toss zucchini and chicken in a baking dish. Channel your inner artist—layer it pretty or dump it in.
3. Pour heavy cream over everything. Think of it as the casserole’s spa day.
4. Season like you mean it. Garlic powder, salt, pepper—give it personality.
5. Top with cheese like it’s a TikTok trend. No cheese left behind.
6. Bake for 25–30 minutes. Wait until the top is golden and bubbly—patience, grasshopper.

Notes

Double the batch and freeze half for future you. Avoid mushy zucchini by not overbaking. Grate your own cheese for perfect melt. Add jalapeños or spinach to flex your flavor muscle. Ground turkey or bacon make great subs for chicken.

Ingredients

Grab these—no fancy health-store pilgrimages required. Pro tip: if your zucchini looks sad, swap it for yellow squash. Nobody’s judging.

• 2 cups cooked chicken, shredded (rotisserie chicken is your lazy BFF)
• 3 medium zucchinis, sliced into half-moons (no need to peel—we’re rebels)
• 1.5 cups shredded cheddar (or go wild with a Mexican blend)
• 1/2 cup heavy cream (the keto holy grail)
• 1 tsp garlic powder (because bland food is a crime)
• Salt and pepper to taste (translation: be generous)

Step-by-Step Instructions

1. Preheat your oven to 375°F. This isn’t a suggestion—cold ovens lead to sad casseroles.
2. Toss zucchini and chicken in a baking dish. Channel your inner artist—layer it pretty or dump it in.
   

   Your call.

   
   
3. Pour heavy cream over everything. Think of it as the casserole’s spa day.
4. Season like you mean it. Garlic powder, salt, pepper—give it personality.
5. Top with cheese like it’s a TikTok trend. No cheese left behind.
6. Bake for 25-30 minutes. Wait until the top is golden and bubbly—patience, grasshopper.

Storage Instructions

Got leftovers? Store in the fridge for up to 4 days—if it lasts that long. For freezer wins, portion it into containers and freeze for up to 3 months. Reheat straight from frozen (add a sprinkle of cheese to revive the magic).

Pro move: Double the recipe and stash half for future you. You’re welcome.

Common Mistakes to Avoid

• Overcooking the zucchini. Mushy veggies = sad casserole. 30 minutes max, folks.
• Skimping on seasoning. This isn’t hospital food. Be bold.
• Using pre-shredded cheese with anti-caking agents. It won’t melt right. Grating is therapy, I promise.

Alternatives and Variations

Not a chicken person?

Swap it for ground turkey or crispy bacon. Dairy-free? Use coconut cream and dairy-free cheese (but maybe whisper an apology to the recipe).

Add jalapeños for heat or spinach for extra greens. This dish is as flexible as your yoga instructor.

Can I freeze this?

Absolutely. Freeze it before baking (tightly wrapped) or after (portion it out).

Thaw overnight in the fridge or reheat from frozen at 350°F until warm.

What’s the best substitute for heavy cream?

Full-fat coconut milk works in a pinch, but it’ll taste slightly sweet. If you’re not strict keto, half-and-half is fine.

How long does it stay fresh?

In the fridge, 4 days max. After that, it’s a science experiment—not a meal.

Is this kid-friendly?

Shockingly, yes.

My niece called it “cheesy chicken cake.” Close enough.

Can I prep it ahead of time?

Assemble it the night before, refrigerate, and bake when ready. Just add 5 extra minutes to the cook time.
