Ingredients Notes
For the Reuben casserole, sourcing quality ingredients is key. Opt for fresh sauerkraut from the refrigerated section of your grocery store for a more authentic taste. Swap pastrami with corned beef if you prefer a less peppery flavor. Use real Swiss cheese for its nutty profile, and if you’re gluten-sensitive, consider using gluten-free rye bread.
Recipe Steps
Step 1
Preheat your oven to 350°F (175°C). Lightly grease a 9×13 inch baking dish with cooking spray or a thin layer of butter.
Step 2
Line the bottom of the baking dish with cubed rye bread, covering it completely.
Step 3
Layer half of the pastrami over the bread cubes, followed by an even layer of half the sauerkraut and half the Swiss cheese.
Step 4
Repeat the layering process with the remaining pastrami, sauerkraut, and Swiss cheese. Top it all with a mixture of mayonnaise and Thousand Island dressing for extra creaminess.
Step 5
Bake in the preheated oven for 45-50 minutes or until the top is golden brown and bubbly. Allow it to cool for 10 minutes before serving.
Storage Options
To store leftovers, cover the casserole tightly with aluminum foil or transfer it to an airtight container and store it in the refrigerator. This will keep it fresh for up to 3 days. For longer storage, wrap the casserole in plastic wrap and place it in a freezer-safe container to freeze for up to 3 months. When ready to eat, thaw overnight in the refrigerator and reheat in the oven at 350°F (175°C) until warmed through.
Variations & Substitutions
For those looking to change things up, consider adding caramelized onions for added sweetness or using turkey pastrami for a lighter option. If you want to make it vegetarian, swap the meat for sautéed mushrooms and spinach. Cheese lovers can add a layer of Gruyère for an extra depth of flavor. For a gluten-free version, use gluten-free bread and confirm all other ingredients are gluten-free as well.
Frequently Asked Questions
Can I make this casserole in advance? Yes, you can prepare the casserole up to a day in advance. Assemble the layers but do not bake it. Cover it tightly with plastic wrap and store it in the fridge. When you’re ready to bake, take it out of the fridge and let it warm slightly on the counter for about 15–20 minutes before baking as directed.
What should I serve with this dish? This casserole pairs well with a simple green salad or steamed vegetables. For added crunch, you can serve it with coleslaw or pickles on the side. A light soup, like a tomatillo or tomato basil soup, also complements the richness of the casserole.
Can I use different types of cheese? Certainly! While Swiss cheese is traditional, feel free to get creative by blending in a sharp cheddar or mozzarella for a melty texture. Just ensure whatever cheese you select matches the flavor profile you desire and melts well.
