Swiss, Sausage, and Thyme Hash Brown Casserole with Poached Eggs and Melted Tomatoes
Breakfast, Brunch
6 Servings

For the Melted Tomatoes

  • 2 pints cherry tomatoes
  • ½ cup olive oil
  • ½ cup balsamic vinegar
  • 1 T sugar (tip, sugar works like salt to bring out additional flavors in foods)
  • ¼ cup fresh basil, chiffonade (tip, stack the leaves and roll them like a cigar, then slice for a quick and neat way to slice basil)
  • salt and pepper to taste

For the Casserole

  • ¼ cup of canola oil
  • 1 medium yellow onion, diced
  • 2 lbs. spicy Italian Pork Sausage
  • 9 cups of Hash Browns
  • 2 cups canola oil
  • salt and pepper
  • 2 T granulated garlic
  • 1 cup of oven roasted ap flour
  • **(trick) toast the flour in a 350 degree oven until it's golden to add a nutty flavor to the roux, it's also a roux short cut when making things like gumbo that need a dark roux
  • 1 cup salted butter
  • 6 cups whole milk
  • 5 cups shredded swiss, divided
  • ¼ cup granulated garlic
  • 1 T fresh thyme leaves
  • salt and pepper to taste
  • 12 eggs, poached in water with a T of white vinegar (tip, this helps the eggs to solidify in the water)
  • salt and pepper


Yields 6

  1. Preheat oven to 275.
  2. Toss the cherry tomatoes in the oil, balsamic, sugar and salt and pepper. Spread them out on a half sheet pan and place in 275 degree oven for about 45 minutes, stirring occasionally. After 45 minutes, remove from heat and smash tomatoes into a sauce, fold in the basil chiffonade and adjust salt and pepper. Set aside.
  3. Increase oven temperature to 425. Grease a 9 x 12 Pyrex dish.
  4. Over medium high heat, get a large cast iron skillet hot. Add oil and brown the diced onions, then add the pork sausage and brown, and crumble, about 5 - 7 minutes. With a slotted spoon remove onion/sausage mixture from pan and set aside.
  5. Add some of the oil to the pre-used cast iron skillet, get it hot and then add the hash browns, spread them out, and let them sit. after about a minute, add more oil and salt and pepper.
  6. When you see the edges starting to brown gently turn the hash browns over with a spatula, trying to not break up too much (you want hash browns that are crispy on the outside and tender in the middle-option...some people just like crispy hash browns in which case, do this in smaller batches, and get them all nice and crispy).
  7. When all cooked through, remove from skillet and set aside. Wipe skillet clear and then add the butter, melt and then add the oven roasted ap flour (this is such a time saver when developing a dark roux-I prefer a roux on this to a bechamel because it has a much more developed flavor, but if you don't have the time, just add the flour and butter and cook down for about 5 minutes to cook out the flavor of the flour).
  8. After about 5 minutes, carefully add the milk to blend...let this simmer for about 5 minutes, then blend in the 3 cups of shredded swiss, garlic, thyme and salt and pepper.
  9. In the greased Pyrex dish, layer first ⅓ of the hash browns, then ⅓ of the cheese sauce and ⅓ of the cooked sausage, repeat 2 more times.
  10. Bake the casserole in the oven for about 30 minutes, while the casserole is heating, poach the eggs. Remove the casserole after 30 minutes (tip: 45 min if you've refrigerated overnight) top with poached eggs and remaining 2 cups of swiss, return to oven for about 3-5 minutes to melt the cheese.
  11. Top with melted tomatoes and serve.
