Tips & Notes

Pro tips

Brown the ground beef in a skillet before adding to the slow cooker to develop flavor and prevent a watery casserole.
Dice the bell pepper and onion small so they soften and distribute evenly throughout the dish during the long cook.
Stir the casserole halfway through cooking (around 3 hours on low) to ensure potatoes cook evenly and prevent sticking at the edges.
Add the shredded cheddar cheese in the last 15–20 minutes of cooking and stir until fully melted for best texture.

Substitutions

Condensed cheddar cheese soup → cream of mushroom or cream of chicken soup (flavor will shift; use extra shredded cheese to compensate)
Ground beef → ground turkey or lean ground pork (cooking time remains the same)
Green bell pepper → red or yellow bell pepper (no functional change; flavor slightly sweeter)

Storage & make-ahead

Cover and refrigerate leftovers for up to 3 days. Reheat in a 350°F oven for 15–20 minutes or microwave until warm throughout.

Common Questions

Can I make this casserole ahead of time?

Yes. Assemble the casserole in the slow cooker insert the night before, refrigerate, and cook on low for 6–7 hours or high for 3–4 hours the next day.
