Bring potatoes, 1 teaspoon salt, and water to cover to a boil in a Dutch oven; cook 8 to 10 minutes. Remove from heat; drain and set aside.
Melt butter in a large skillet over medium-high heat; add chopped onion, and sauté 12 to 15 minutes or until golden brown.
Layer half of potatoes in a lightly greased 13- x 9-inch baking dish or 2 (8-inch) square baking dishes; sprinkle with 1/2 teaspoon salt and 1/4 teaspoon pepper. Top with half each of onions, Gruyère cheese, and Cream Sauce. Repeat layers once, ending with Cream Sauce.
Bake at 350° for 1 hour and 15 minutes or until golden brown.
*1 (8-ounce) block Swiss cheese, shredded, or 1 (8-ounce) block sharp white Cheddar cheese, shredded, may be substituted.
Instead of layering, I sauteed the onions and then mixed them into the sauce, along with the cheese. Poured over the potatoes in a 2 qt. baking dish once it was melted and baked until bubbly. Delicious!
I recently made this casserole for a dinner party. I was hesitant to try a new recipe when entertaining, but Love Gruyere cheese, and have trusted Southern Living Recipes all of my life, so I took the leap. I am so glad that I did, it is absolutely delicious and the presentation is beautiful. The recipe takes a little extra time and preparation, but is well worth it...
