Creamy Tuna in White Sauce: A Culinary Comfort Classic

My grandmother, bless her heart, wasn’t exactly known for her elaborate culinary creations. But she had a knack for simple, comforting dishes that filled you with warmth and nostalgia. This Tuna in White Sauce is a direct descendant of one of her go-to recipes. I remember sitting at her kitchen table, the aroma of simmering potatoes and creamy sauce filling the air, as she ladled a generous portion onto my plate. Each bite was pure, unadulterated comfort, a taste of home that I still crave to this day.

Recipe Overview

• Prep Time: 15 minutes
• Cook Time: 25 minutes
• Total Time: 40 minutes
• Servings: 4
• Yields: 4 Bowls
• Dietary Type: Pescatarian

Ingredients

• 3 large potatoes, peeled and chopped
• ½ onion, chopped
• 1 celery rib, chopped
• 2 (3 ounce) cans tuna, drained
• ½ cup frozen peas, thawed
• 2-3 cups water, to cover
• 2 tablespoons cornstarch
• ¼ cup cold water
• ¼ teaspoon salt and pepper, to taste
• 2 tablespoons butter
• ¼ cup milk

Equipment Needed

• Saucepan
• Measuring cups and spoons
• Knife
• Cutting board

Instructions

1. Begin by melting half of the butter (1 tablespoon) in a saucepan over medium heat.
2. Add the chopped onion and celery to the pan and sauté until softened, approximately 5-7 minutes, stirring occasionally to prevent burning. The onion should become translucent and the celery slightly tender.
3. Add the peeled and chopped potatoes to the saucepan, followed by the salt, peas, and enough water to completely cover the potatoes. Typically, this requires between 2-3 cups, but adjust as needed to ensure all the potatoes are submerged.
4. Bring the mixture to a boil over high heat, then reduce the heat to a simmer. Cook until the potatoes are tender, approximately 15-20 minutes. You should be able to easily pierce a potato with a fork. During this time, allow the liquid to reduce by roughly one-third.
5. While the potatoes are cooking, drain the tuna from its can(s).
6. Once the potatoes are cooked, add the drained tuna to the saucepan and heat through.
7. Pour in the milk to achieve your desired soup-like consistency. The amount of milk may need to be adjusted based on how much liquid has reduced during cooking.
8. Season with pepper, and add the remaining butter (1 tablespoon). Stir until the butter is melted and incorporated.
9. In a small bowl, create a slurry by thoroughly mixing the cornstarch and cold water. This step is crucial to prevent lumps in the final sauce.
10. Slowly pour the cornstarch slurry into the saucepan while continuously stirring.
11. Increase the heat to medium and bring the mixture to a simmer, stirring constantly until the sauce thickens to your desired consistency. This usually takes about 2-3 minutes. Be patient and continue stirring to avoid scorching.
12. Taste and adjust the seasoning as needed. Add more salt and pepper to taste.
13. Optionally, you can mash some of the potatoes with a fork or potato masher to create a thicker, creamier soup. Alternatively, serve as is.
14. Serve hot, with toasted bread for dipping, if desired.

Expert Tips & Tricks

• For a richer flavor, use chicken broth instead of water when cooking the potatoes.
• To avoid lumps in the white sauce, ensure the cornstarch slurry is thoroughly mixed before adding it to the hot liquid. Whisking constantly while pouring is key.
• If the sauce becomes too thick, add a splash of milk or water to thin it out.
• To make this dish ahead of time, prepare it up to the point of adding the tuna and milk. Store it in the refrigerator and add the tuna and milk when reheating. This prevents the tuna from becoming dry.
• A pinch of nutmeg adds a warm, subtle flavor to the white sauce.
• For a smoother sauce, use an immersion blender to partially blend the soup before adding the tuna.

Serving & Storage Suggestions

Serve this Tuna in White Sauce hot, garnished with a sprinkle of fresh parsley or a grind of fresh black pepper. It’s delicious served over mashed potatoes, boiled rice, or simply enjoyed on its own with a side of crusty bread for dipping.

Leftovers can be stored in an airtight container in the refrigerator for up to 3 days. To reheat, gently warm on the stovetop over low heat, stirring occasionally, or microwave in 30-second intervals, stirring in between, until heated through. Add a splash of milk or water if the sauce has thickened too much during storage. I don’t recommend freezing, as the texture of the potatoes may change.
