Pinterest Image is a layered baked dish built on a base of potatoes, a creamy garlic sauce, and a sharp cheese crust. It looks like a project and cooks like a weeknight dinner: 15 minutes of prep, 35 minutes in the oven at 400F (205C), and a 10-minute rest before you cut it.

The numbers matter here. Six servings at roughly 285 calories each comes from 2 pounds of potatoes, 1 cup of whole milk, 4 ounces of cheddar, and a measured amount of butter and flour for the sauce. Nothing is guessed; the sauce is a 1:1 butter-to-flour roux, which thickens reliably at 2 cups of liquid.
The main risk is undercooking the potatoes or letting the sauce break. Slicing at 1/8 inch (3mm) and simmering the sauce until it coats a spoon solves both. Follow the temperatures exactly and you get a clean slice every time.
Why You'll Love This Recipe
About the Ingredients
2 lb (900g) Yukon Gold potatoes, peeled and sliced 1/8 inch (3mm) thick
Yukon Gold holds shape and turns creamy; russets work but release more starch. Buy firm potatoes with no green patches and skip waxy red potatoes, which stay firm and slice poorly.
3 tbsp (42g) unsalted butter
Use unsalted so you control the salt level against the cheese. Salted butter works if you cut the added salt to 1/4 tsp.
3 tbsp (24g) all-purpose flour
This is the roux thickener at a 1:1 ratio with butter. For gluten-free, substitute 2 tbsp cornstarch and whisk it into cold milk before heating.
1 1/2 cups (360ml) whole milk
Whole milk gives body; 2% works but the sauce will be thinner. Do not use skim milk, which can break under heat.
1/2 cup (120ml) heavy cream
Cream adds richness and buffers the sauce against curdling. Half-and-half is a fine substitute; avoid milk plus butter as a swap.
2 cloves garlic, minced (about 2 tsp)
Fresh garlic only here; jarred garlic tastes flat after baking. Add it to the butter off heat so it does not burn.
4 oz (115g) sharp cheddar, grated
Sharp cheddar gives the browned crust. Gruyere melts smoother; pre-shredded cheese contains anti-caking starch and browns unevenly.
1/2 tsp salt plus 1/4 tsp black pepper
Season the sauce, not just the top, because the potatoes absorb salt slowly. Kosher salt measures differently than table salt, so weigh if you can.
1/4 tsp freshly grated nutmeg
A small amount rounds out the cream sauce without tasting like dessert. Skip it if you dislike it; dried thyme (1/4 tsp) is a good alternative.
1 tbsp chopped fresh chives, for finishing
Adds color and a mild onion note. Thin-sliced scallion greens or parsley are direct substitutes.
Tips & Tricks
Slice Evenly or Bake Unevenly
Cut potatoes at a consistent 1/8 inch (3mm). Thick slices stay raw in the center while thin ones dissolve, so use a mandoline if you have one.
Thicken Before It Hits the Oven
Simmer the sauce until it coats the back of a spoon, about 3 minutes. A thin sauce steams the potatoes and leaves a watery casserole.
Rest Before Slicing
Wait 10 minutes after baking. The starch sets as it cools, so the first slice holds its shape instead of sliding apart.
Watch the Crust, Not the Clock
Broil only in the last 2 minutes if the top is pale. Cheese goes from golden to bitter in under 60 seconds at high heat.
Pro Tips
Step-by-Step Instructions
1. Heat the oven and prep
Set the oven to 400F (205C). Grease a 9×13 inch (23x33cm) baking dish with 1 tsp of the butter. Peel and slice the potatoes at 1/8 inch (3mm) and keep them in cold water so they do not brown.
2. Build the roux
Melt the remaining butter in a saucepan over medium heat at about 300F (150C) until it foams but does not brown, roughly 2 minutes. Whisk in the flour and cook 1 minute until it smells toasted and looks like wet sand.
3. Finish the sauce
Pour in the milk and cream in a steady stream while whisking. Add the garlic, salt, pepper, and nutmeg. Simmer 3 to 4 minutes until the sauce coats a spoon, then pull it off heat and stir in half the cheddar until it melts smoothly.
4. Layer the dish
Drain and pat the potatoes dry. Spread one third in the dish, pour on one third of the sauce, and repeat twice, finishing with sauce. Press down gently so the liquid sits level with the top layer.
5. Bake covered
Cover tightly with foil and bake 25 minutes at 400F (205C). The edges should be bubbling and a knife at the center should meet little resistance.
6. Add the crust
Remove the foil, scatter the remaining cheddar over the top, and bake uncovered 8 to 10 minutes until the cheese is golden brown and the center reads 205F (96C). If it is still pale, broil 2 minutes.
7. Rest and finish
Let the dish sit 10 minutes so the starch sets. Scatter the chives over the top, cut into 6 portions, and serve hot.
Delicious Variations
Bacon and Gruyere
Swap cheddar for Gruyere and add 4 slices of cooked, crumbled bacon between layers for a smokier profile.
Herb and Parmesan
Replace cheddar with 3 oz Parmesan and stir 1 tsp dried thyme into the sauce for a sharper, drier crust.
Spicy Southwest
Add 1 diced jalapeno to the roux and use pepper jack; finish with cilantro instead of chives.
How to Store Pinterest Image
Refrigerator
Store covered in the refrigerator up to 4 days. Cool within 2 hours of baking to avoid bacterial growth.
Freezer
Freeze portions in an airtight container up to 2 months. The sauce may separate slightly, so reheat gently rather than at high heat.
Reheating
Reheat covered at 350F (175C) for 15 to 20 minutes, or microwave single portions 2 minutes. Add a splash of milk if it looks dry.
Frequently Asked Questions
Q: Can I make Pinterest Image ahead of time?
Yes, assemble it up to 24 hours ahead, cover, and refrigerate before baking. Add 10 minutes to the covered bake time because the dish starts cold.
Q: Why did my sauce turn grainy?
The sauce broke because the heat was too high or the cheese went in boiling. Keep the sauce at a bare simmer and add cheese off the heat, stirring until smooth.
Q: Can I use russet potatoes instead of Yukon Gold?
Yes, but russets release more starch and give a softer, less defined slice. Soak the slices 10 minutes in cold water and pat them dry before layering.
Q: How do I know the potatoes are fully cooked?
A knife at the center should slide in with no resistance and the center should read 205F (96C). If it resists at all, bake 5 more minutes covered.
Q: Is this dish gluten-free?
Not as written because of the flour. Substitute 2 tbsp cornstarch whisked into cold milk and the sauce will still thicken, though slightly glossier.
Measure the potatoes, weigh the cheese, and set a timer instead of guessing. If you bake it once at 400F (205C) with the covered and uncovered stages, you will have a repeatable result you can adjust on purpose. Stay sharp, stay solvent.
