Pro Tips Before You Start
Cut the potatoes into even chunks so they cook at the same rate.

Whisk the cream slowly into the flour mixture to keep the sauce smooth.
Cover tightly with foil during the first bake so the potatoes soften properly.
Let the dish rest for a few minutes before serving so the sauce can settle slightly.
How to Make Cheesy Tuscan Bacon Gratin Potatoes
Step 1 – Prep the oven and potatoes
Preheat the oven to 400°F. Scrub the potatoes clean and cut them into 1-inch chunks.
Step 2 – Layer the base
Arrange the cubed potatoes, fresh spinach, and crumbled bacon in a greased 9×13 baking dish.
Step 3 – Cook the aromatics
In a large heavy skillet over medium heat, add the butter, onion, and garlic. Cook for 5 to 6 minutes until the onion is soft and translucent.
Step 4 – Build the sauce
Whisk in the flour, kosher salt, black pepper, and nutmeg. Stir until the flour is fully absorbed.
Step 5 – Add the cream
Slowly pour in the heavy cream while whisking. Cook for 8 to 10 minutes until the sauce thickens.
Step 6 – Melt in the cheese
Whisk in half of the provolone cheese and the chopped sun-dried tomatoes. Stir until the cheese is melted and the sauce is smooth.
Step 7 – Assemble the gratin
Pour the sauce evenly over the potatoes, spinach, and bacon in the baking dish.
Step 8 – Bake covered
Cover the dish tightly with foil and bake for 30 minutes.
Step 9 – Finish uncovered
Remove the foil and bake for 20 minutes. Top with the remaining provolone cheese.
Step 10 – Bake until hot and melty
Return to the oven for 10 more minutes, then serve hot.
What to Serve Them With
Serve this with roasted chicken, steak, or pork chops for a hearty dinner.
It also pairs well with grilled sausages or baked salmon.
Add a crisp green salad or roasted vegetables on the side to balance the richness.
Variations / Substitutions

Use kale instead of spinach if that’s what you have on hand.
