Potato, Kale, and Kielbasa Casserole for Two

The first time I tasted anything close to this casserole, it was a frigid Chicago evening. My Polish grandmother, Babcia, had been simmering a hearty potato and kielbasa soup all day, the aroma weaving its way through the entire house. It was deeply savory, comforting, and warming from the inside out. Years later, craving that same feeling, I adapted her soup into this cozy casserole, perfectly sized for a weeknight dinner for two.

Recipe Overview

• Prep Time: 20 minutes
• Cook Time: 30 minutes
• Total Time: 50 minutes
• Servings: 2
• Yield: 1 casserole
• Dietary Type: Not Gluten-Free

Ingredients

• 1 lb potato, peeled and quartered
• 1 tablespoon unsalted butter
• ½ cup chicken broth, divided
• 2 teaspoons cider vinegar
• Salt and pepper to taste
• ½ lb kale, stems removed
• ½ cup Swiss cheese, grated
• ⅓ lb smoked kielbasa, sliced
• 1 small onion, thinly sliced
• ¼ cup Swiss cheese, grated

Equipment Needed

• Dutch oven
• Slotted spoon
• Colander
• Potato ricer (or potato masher)
• Large bowl
• Buttered casserole dish (approximately 6×8 inches)
• Large skillet

Instructions

1. Arrange a rack in the middle of the oven and preheat to 450 degrees F.

2. In a dutch oven, combine the potatoes with enough water to cover them by 2 inches. Bring the water to a boil, and boil the potatoes for 15 minutes, or until they are tender. The potatoes should be easily pierced with a fork.

3. Transfer the potatoes with a slotted spoon to a colander, reserving the cooking liquid. Force them through a ricer into a bowl. (Alternatively, mash until smooth with no chunks using a potato masher. Achieving a smooth, lump-free consistency is key for the casserole’s texture.)

4. Add the butter, ¼ cup of the chicken broth, the cider vinegar, and salt and pepper to taste. Combine the mixture well until everything is incorporated and creamy.

5. Bring the reserved potato cooking liquid to a boil in the dutch oven.

6. Coarsely chop the kale leaves. Add the kale to the boiling water, and boil it for 10 minutes, or until it is crisp-tender. Some slight resistance when bitten into is ideal.

7. Drain the kale in the colander. Refresh it under cold water to stop the cooking process and preserve its vibrant color. Then, press out the excess water. Removing excess water prevents a soggy casserole.

8. Stir the kale and ½ cup of the Swiss cheese into the potato mixture. Spread the mixture evenly in a buttered casserole dish.

9. In a large skillet, brown the kielbasa over moderate heat. Work in batches if necessary to avoid overcrowding the pan, which can steam the sausage instead of browning it. Transfer the browned kielbasa to a bowl with the slotted spoon. This leaves the flavorful rendered fat in the skillet.

10. In the fat remaining in the skillet, cook the onions over moderate heat, stirring frequently, until they are golden and softened. Don’t rush this step. Allowing the onions to caramelize adds depth of flavor to the casserole. Stir them into the bowl with the kielbasa.

11. Scatter the kielbasa mixture evenly on top of the potato mixture in the casserole dish. Sprinkle the remaining ¼ cup Swiss cheese on top. Pour the remaining ¼ cup broth evenly over the surface of the casserole.

12. Bake the casserole until heated through and the cheese is melted and bubbly, about 20 minutes. The internal temperature should reach at least 165°F. If the top is browning too quickly, loosely tent the casserole dish with foil.

NOTE: The casserole may be prepared up to step 11 one day in advance and kept covered and chilled. Bring to room temperature for approximately 30 minutes before baking.

Expert Tips & Tricks

• For extra flavor: Add a clove of minced garlic to the onions as they cook. A pinch of red pepper flakes can also add a subtle kick.
• Achieve the perfect mashed potato consistency: Using a ricer yields the smoothest results. If using a masher, be careful not to overwork the potatoes, as this can make them gummy.
• Ensure even cooking: Cut the potatoes into uniform sizes for even cooking.
• Prevent a soggy casserole: Be thorough in removing excess water from the kale.
• Elevated presentation: Garnish with fresh parsley or chives after baking.

Serving & Storage Suggestions

Serve the Potato, Kale, and Kielbasa Casserole hot from the oven. It’s a complete meal on its own, but pairs well with a simple side salad.

Leftovers can be stored in an airtight container in the refrigerator for up to 3 days. To reheat, microwave in 1-minute intervals until heated through, or bake in a preheated oven at 350°F until warmed. Freezing is not recommended, as the texture of the potatoes may change.
