  • Prep

  • Cook

  • Ready In

  1. Preheat an oven to 400 degrees F (200 degrees C). Combine the potatoes and spinach in a 9x13-inch baking dish; set aside.
  2. Melt 3 tablespoons of butter in a saucepan over medium-low heat. Stir in the onion, and cook until dark brown, about 15 minutes. Stir in the garlic and flour; cook 1 minute more. Season with salt, and stir in the milk and cream. Bring to a simmer over medium heat; cook and stir until the sauce has thickened, about 10 minutes. Stir in 3/4 of the Muenster cheese until melted, and pour over the potatoes.
  3. Cover the potatoes with aluminum foil, and bake in the preheated oven 30 minutes. Uncover, and cook 20 minutes more, then sprinkle with the remaining Muenster cheese, return to the oven, and bake until the potatoes are tender and the cheese is bubbly, about 10 minutes more.

Footnotes

  • Tip
  • Aluminum foil helps keep food moist, ensures it cooks evenly, keeps leftovers fresh, and makes clean-up easy.

This is good, but missing something; just don't know what. To be fair, I cut the recipe in half and used only whole milk. I'm not sure if that makes a big difference. I will try this again wi...

These potatoes are outstanding! I followed the recipe as written, and couldn't be more pleased, even the cook times are spot on! The sauce was perfect in 10 minutes, and the bake time is perfect...

Hubby said to give this one 6 stars...It was that good! My mom insisted she had a block of muenster cheese, but of course, she didn't, lol, so I ended up using Butter Kase, but I could totally s...

Delicious! My new favorite au gratin recipe. I added a little extra salt just for personal preference.

This recipe is delicious and I’ve made it several times, with modifications, in the last few months. Because of the high fat content as written I use olive oil instead of butter and 2% milk inst...

Abolutely Divine! I had no cream, so used 1 3/4c milk + 1/4c sour cream. Also, after baking 30 min covered & 20 uncovered, I put back in 300 degree oven, covered for about 30 min only because my...

We thought this came out very well. I think I'd use a stronger-flavored cheese in the future, and I'd probably caramelize another onion or two as they were lost in mine. The recipe calls for mor...

I made this tonight to go with beef tenderloin. Wow, these were really good. My father and husband thought they were great too. I did change a couple things to go with what I had on hand. Yuk...

I was torn between four or five stars. I opted to go with four because I believe a different cheese would have been better and alot cheaper, too. I couldn't get shredded muenster, so I had to bu...
