Caramelized Onion and Mushrooms, Spinach Potato AuGratin with Sweet Italian Sausage
I found a recipe on here yesterday...posted about a year ago...I don't even know if the gal is still on here. But I will link this recipe to hers. I found this and thought OMG yum! Like I so often do ;) Then today, I was looking in my frig and thought, I bet those sausages would be good in here and them mushrooms and well...since I didn't have muentster cheese...decided to just rewrite history a little bit. So I'm posting this as mine, but also thanking Lana Bade for the inspiration.

How to Make Potatoes AuGratin w/Italian Flair


  1. Spray a 4 quart casserole dish or 9x13 pan, toss together the potatoes and spinach in casserole. Set aside.
  2. In large skillet, heat oil and add sweet italian sausage, using utensil to break up as it cooks, when browned, drain and spoon sausage over potato mixture. Toss to mix. Sprinkle parmesan cheese over potato mixture. Set aside.
  3. In the same skillet add 3T butter, sliced onions and mushrooms, saute over medium heat until caramelized. (about 10 min) add garlic and cook for another couple minutes. Then add 3 more tablespoons of butter, when melted, stir in flour and cook until flour turns brownish, about a min or two. Then add thyme, rosemary, basil, salt and pepper stir well, then add warm milk and cream, whisking until combined, continuing to whisk until it just starts to boil, remove from heat, add 2 cups of cheese, reserving the last cup til later, stirring until melted and incorporated. Pour cheese mixture over potato mixture in casserole dish.
  4. Cover with foil and bake at 375 for 25 min. Remove from oven, remove foil and sprinkle with remaining cheese, put back in oven uncovered 15-20 minutes longer until cheese is lightly browned.
  5. Adding remaining cheese in step 4 is completely optional... But I would continue to cook the 15-20 minutes longer.
