The first time I threw this dish together, it wasn’t planned. It was one of those midweek nights where the fridge looked like a puzzle I didn’t feel like solving—just some leftover mashed potatoes, a handful of frozen chicken tenders, and half a block of cheddar. I stood there, barefoot and tired, staring at the fridge light like it was going to magically feed us all. And then I thought: what if I just stacked it all together?
Fifteen minutes later, my kitchen smelled like pure comfort. My daughter peeked in from the living room and said, “Mom, it smells like a drive-thru in here—but better.” That made me laugh out loud. I poured a little gravy on top, handed out forks, and we ate it right out of the pan at the kitchen counter like it was the best thing we’d ever tasted.
Since then, this casserole has earned a permanent spot in our dinner rotation. It’s everything I want in a meal: fast, hearty, kid-approved, and adaptable. This one’s for all the fellow parents out there who need a win at 6 PM with minimal cleanup and full bellies.
Short Description
A comforting, layered casserole with creamy mashed potatoes, sweet corn, melty cheddar, crispy chicken tenders, and rich brown gravy—quick to make, kid-friendly, and great for busy weeknights.
Key Ingredients
- 5–6 cups prepared mashed potatoes
- 1 cup corn kernels (fresh, canned, or frozen)
- 1 cup cheddar cheese, freshly grated
- 8 chicken tenders (frozen or homemade)
- Brown gravy, prepared (homemade or from a packet)
Tools Needed
- 9×13 inch casserole dish
- Oven
- Small saucepan (for gravy)
- Sharp knife
- Mixing spoon
- Measuring cups
Cooking Instructions
Step 1: Preheat and Prep
Preheat your oven to 400°F. If using frozen chicken tenders, let them sit at room temperature for about 5 minutes—this softens them just enough to slice without crumbling.
Step 2: Layer the Mashed Potatoes
Warm your mashed potatoes slightly if they’re cold (a minute or two in the microwave does the trick). Then spread them evenly across the bottom of a 9×13 inch casserole dish.
Step 3: Add Corn and Cheese
Sprinkle the corn evenly over the potatoes, followed by a generous layer of freshly grated cheddar cheese. The sweet corn pops through the creamy potato base, and the cheese helps bind everything together.
Step 4: Add the Chicken
Slice the chicken tenders into bite-sized chunks and scatter them over the top. No need for perfection—just make sure it’s spread out for even bites.
Step 5: Bake Until Golden
Bake uncovered:
– 15 minutes for homemade chicken tenders
– 20 minutes for frozen ones
The casserole is ready when everything is hot and the cheese is melted and bubbling at the edges.
Step 6: Gravy Time
While it bakes, prepare your brown gravy on the stovetop. Once the casserole is out, drizzle the hot gravy across the top just before serving. Start light—you can always serve extra on the side!

Mistakes to Avoid & Solutions
Using cold mashed potatoes:
They won’t spread easily and may clump.
Solution: Warm them in the microwave or stovetop before layering.
Skipping the gravy:
It ties everything together.
Solution: Even a quick packet gravy adds richness—don’t skip it.
Overbaking:
Dry chicken and burnt cheese can ruin the dish.
Solution: Set a timer and stick to the recommended time based on the chicken type.
Uneven chicken cuts:
Leads to inconsistent texture.
Solution: Slice chicken tenders into uniform bite-sized pieces.
Using pre-shredded cheese:
It won’t melt as smoothly.
Solution: Shred your own cheddar for that creamy, melt-in look.
Serving and Pairing Suggestions
Serve it family-style right from the baking dish with extra gravy on the side.
Add a fresh green salad or steamed broccoli for balance.

Storage and Reheating Tips
Refrigerate in an airtight container for up to 4 days.
Reheat individual portions in the microwave for 2–3 minutes.
For best texture, reheat in the oven at 350°F for 15–20 minutes, covered with foil.
Avoid freezing fully assembled casserole—it changes the texture. Instead, freeze the chicken or mashed potatoes separately.
FAQs
1. Can I use rotisserie chicken instead of tenders?
Yes! Just shred or cube it and layer as directed. Reduce baking time by 5 minutes since it’s already cooked.
2. What’s the best type of mashed potato to use?
Creamy, buttery ones work best—russet or Yukon gold varieties hold up well in baking.
3. Can I add more vegetables?
Absolutely. Peas, diced carrots, or green beans make great additions. Just pre-cook or thaw before layering.
4. Is there a gluten-free version?
Use gluten-free chicken tenders and a certified GF gravy mix. Everything else is naturally gluten-free.
5. How do I keep the cheese from getting greasy on top?
Use freshly grated cheese and avoid overbaking. If needed, add a light layer of foil during the last 5 minutes of baking.
Tips & Tricks
Let your mashed potatoes be slightly chunky for more texture.
A dash of garlic powder or smoked paprika in the potatoes adds extra depth.
Add a thin layer of cheese between each layer for gooey goodness in every bite.
Want extra crisp? Pop the broiler on for 1–2 minutes at the end—just watch closely!
