• 1 medium yellow onion, thinly sliced (sweet varieties like Vidalia add nice flavor)
• 2 cups shredded cheddar cheese (sharp cheddar gives the best flavor punch)
• 1 cup chicken broth (low-sodium lets you control the salt level)
• ½ cup heavy cream (for extra richness, or substitute whole milk)
• 2 tbsp all-purpose flour (to thicken the sauce naturally)
• 1 tsp garlic powder (not garlic salt—we’re adding salt separately)
• ½ tsp black pepper (freshly cracked adds the best flavor)
• ¼ tsp salt (add more at the end if needed after tasting)
• 2 tbsp chopped fresh parsley (for garnish, adds fresh color and flavor)

Instructions

1. Spray your 6-quart slow cooker insert thoroughly with cooking spray to prevent sticking.
2. Layer half of the sliced potatoes evenly across the bottom of the slow cooker.
3. Scatter half of the diced ham evenly over the potato layer.
4. Sprinkle half of the sliced onions over the ham layer.
5. Repeat layers with remaining potatoes, ham, and onions.
6. In a medium bowl, whisk together chicken broth, heavy cream, and flour until completely smooth—no lumps should remain.
7. Stir garlic powder, black pepper, and salt into the broth mixture until fully incorporated.
8. Pour the liquid mixture evenly over the layered ingredients in the slow cooker.
9. Cover and cook on LOW heat for 6 hours until potatoes are fork-tender—test by piercing a center potato slice with a fork; it should slide through easily.
10. Sprinkle shredded cheddar cheese evenly over the top of the casserole.
11. Cover and continue cooking on LOW for 15 minutes until cheese is fully melted and bubbly.
12. Let the casserole rest uncovered for 10 minutes before serving—this allows the sauce to thicken slightly.
13. Garnish with fresh chopped parsley just before serving.

Zesty cheese melts into every nook of the tender potatoes, while the ham adds savory depth that makes this feel like a special occasion meal. Try serving it straight from the slow cooker with crusty bread for dipping into that creamy sauce, or spoon it over toasted biscuits for the ultimate comfort food experience.
