Reuben Squares Ingredients

• Gather your pantry staples and let’s make these tasty squares!

For the Base and Topping

Refrigerated Crescent Rolls (2 tubes, 8-oz each) – They create a buttery, flaky crust that’s easy to work with.
Melted Butter (2 Tbsp.) – Enhances flavor and creates a golden hue; olive oil works too for a lighter crust.

For the Filling

Corned Beef (1/2 lb.) – The savory star of these Reuben Squares; pastrami can be a delightful alternative.
Swiss Cheese (6 slices) – Adds that creamy, melty texture; Gruyère is a tasty upgrade!
Sauerkraut (3/4 cup) – Brings tang and depth; rinse and drain to adjust the acidity.
Mayonnaise (1/4 cup) – Acts as a binding agent for moisture; Greek yogurt is a healthier substitute.

For Seasoning

Kosher Salt – Enhances all the flavors in your dish; feel free to substitute with regular salt but adjust the amount.
Caraway Seeds – Adds a traditional rye flavor; omit if you’re not a fan.
Ketchup (1 Tbsp.) – Balances the bite with sweetness; BBQ sauce can add a smoky flavor twist.
Horseradish (1 Tbsp.) – Adds a kick of spice; adjust based on your heat preference.
Worcestershire Sauce (1 tsp.) – Infuses umami richness; soy sauce can be used in a pinch.
Granulated Sugar (1 tsp.) – Balances acidity; honey is a natural alternative if preferred.
Paprika (1/4 tsp.) – Enhances color and adds a hint of smokiness; smoked paprika is even better!
Freshly Ground Black Pepper – Complements the overall flavor profile of these squares.

With these wholesome ingredients, you’ll be on your way to whipping up unforgettable Reuben Squares that every guest will rave about!

Step‑by‑Step Instructions for Reuben Squares

Step 1: Preheat the Oven
Begin by preheating your oven to 375°F (190°C) to prepare for baking your Reuben Squares. This ensures that the squares will bake evenly and develop that perfect golden crust. While the oven warms, gather your ingredients and baking equipment to streamline the cooking process.

Step 2: Prepare the Baking Dish
Lightly spray a 9×13-inch baking dish with cooking spray to prevent sticking. Unroll one tube of refrigerated crescent rolls and lay the dough evenly across the bottom of the dish, pressing the seams together to create a solid base. This flaky crust will provide the perfect foundation for your savory filling.

Step 3: Parbake the Crust
Place the baking dish in the preheated oven and parbake the crust for about 10 minutes. You’re looking for a lightly golden hue; this parbaking step will help prevent a soggy bottom later. Keep an eye on it as the time approaches to ensure it doesn’t over-bake.

Step 4: Layer the Ingredients
After parbaking, take the dish out of the oven and start layering your filling. Evenly distribute the corned beef over the crust, followed by the Swiss cheese slices and rinsed sauerkraut. If you’re adding additional toppings like mayonnaise or seasonings, do so at this stage to infuse flavor throughout the Reuben Squares.

Step 5: Add the Top Layer
Open the second tube of crescent rolls and carefully lay over the filling, sealing the edges by pinching the dough. This top layer will encase the delicious filling, ensuring every bite of your Reuben Squares is filled with flavor. Smooth out any seams for an even bake.

Step 6: Brush and Bake
Before returning your Reuben Squares to the oven, brush the top with melted butter to achieve a beautiful, golden finish. If you like, sprinkle caraway seeds over the top for added flavor. Bake for an additional 25 to 30 minutes, or until the crust is golden brown and bubbly.

Step 7: Cool & Slice
Once out of the oven, allow the Reuben Squares to cool for a few minutes to set. This step is important; letting them rest will help maintain their shape when slicing. After cooling, use a sharp knife to cut them into squares, ready to serve warm at your next gathering!

Make Ahead Options

These Reuben Squares are perfect for meal prep enthusiasts! You can assemble the squares up to 24 hours in advance by layering all ingredients in the baking dish and tightly covering it with plastic wrap before refrigerating. This not only saves you time but ensures all the flavors meld beautifully. When you’re ready to serve, simply remove them from the fridge and bake as directed, adding an extra 5-10 minutes to the baking time if they’re chilled. To maintain their delightful texture, ensure the crust is parbaked for about 10 minutes before adding the filling. With these make-ahead tips, you’ll have scrumptious Reuben Squares at your fingertips whenever hunger strikes!

Reuben Squares Recipe FAQs

How do I choose the right ingredients for Reuben Squares?
Absolutely! For the best Reuben Squares, look for fresh corned beef from the deli counter—avoid packaged varieties that may taste overly processed. When selecting your sauerkraut, opt for a brand that’s packed in jars rather than cans for a fresher taste. For the Swiss cheese, a good quality aged cheese can elevate the flavor profile. Lastly, select crescent rolls that are fresh and free of any dark spots; you want them light and flaky to complement your filling!

What’s the best way to store leftovers?
Very good question! Leftover Reuben Squares can be stored in an airtight container in the fridge for up to 3 days. Be sure they’re completely cooled before sealing to maintain their delicious texture. If you find yourself with extras after a gathering, simply reheat them in the oven at 375°F (190°C) for about 10-15 minutes until heated through.

Can I freeze Reuben Squares, and how should I do it?
Yes, you can absolutely freeze Reuben Squares! After they’ve cooled completely, wrap each square in plastic wrap individually, then place them in a freezer-safe bag or container—this helps prevent freezer burn. They’ll stay fresh for up to 2 months. To reheat, bake them straight from the freezer at 375°F (190°C) for about 25-30 minutes until they are warmed through and crispy.

What if my Reuben Squares turn out soggy?
If your squares turn out soggy, don’t worry, it happens! This can often be resolved by making sure that the bottom crust is fully parbaked—a light golden color is what you’re aiming for. Additionally, make sure to drain the sauerkraut properly; excess moisture can make your filling wet. If it was too late and you already baked them, consider serving them with a side of dipping sauce like Russian dressing to enhance the overall experience.

Are there any dietary considerations I should be aware of when making Reuben Squares?
Indeed! If you’re cooking for a crowd, be mindful of any allergies or dietary restrictions. Make sure to ask if anyone has gluten sensitivities since crescent rolls contain gluten. For lactose intolerance, you can substitute Swiss cheese with a lactose-free cheese option or even try a vegan cheese alternative. Lastly, if you’re trimming fat, consider using low-fat mayonnaise and leaner cuts of corned beef or turkey.

Can pets eat Reuben Squares?
While it might be tempting to share, it’s generally not safe for pets to indulge in Reuben Squares. Ingredients like onion and garlic (often found in sauces) can be harmful to dogs and cats. Even the bread may not sit well with them, causing digestive issues. Always stick to pet-safe treats if your furry friends are looking for a nibble!
