How to make tuna potato salad
This is going to be a bit different from your standard tuna salad or potato salad recipes. We’re skipping over the mayo and packing in some extra veggies to make this a one-bowl meal that will satisfy the family.
To make this hearty dish, you only need 10 ingredients – most of which are simple things you probably already have on hand in your pantry, freezer, or fridge:
- Olive oil
- Frozen spinach
- Blue Harbor Wild Albacore Tuna in Water with Sea Salt
- Cherry Tomatoes
- Red onion
- Grainy Mustard
- Cider Vinegar
You might notice I personally use Blue Harbor’s canned tuna – definitely grab it for this recipe. Their albacore tuna is high quality with a great taste. Plus, Blue Harbor is also invested in sustainability, making sure they fish from waters with healthy levels of fish species, and ensuring minimal ecosystem impacts. You can find locations where it’s sold (or buy it online) using their product locator!
Alright, got all your ingredients? You’ll start by chopping up those potatoes and tossing them in a little olive oil and salt, then roasting them in the oven. Roasting helps bring out the flavor and makes for that perfect crispy-outside-yet-tender-inside texture.
While the potatoes are cooking you can get everything else ready for the salad, like chopping up the tomatoes, cooking your frozen spinach (I just microwave it!), and preparing your honey mustard dressing.
Then when the potatoes are done, you’re ready to toss everything together. Voila – your dinner is ready.
It might seem like an odd combination, but it is so darn delicious! My husband’s reaction when he tasted a bite? “Wow. I wasn’t expecting that.” I inquired for more and he replied “When you think tuna potato salad it sounds a little weird – but this is really, really good.”
One of the best things about this salad is it’s really flexible depending on what you have on hand or what you can find at the store.
- If you can’t find red potatoes: Any potato will work! Yukon gold, white, or any of the baby potato varieties are excellent substitutions.
- If you can’t find frozen spinach: Fresh spinach or kale can both be used! Just sauté it for a few minutes first. Of look for other frozen greens – like frozen mustard greens or collard greens. Those can be substituted in as well.
- If you can’t find cherry tomatoes: See if you can find beefsteak tomatoes, roma tomatoes, or tomatoes on the vine. If not, substitute in about half of a can of diced tomatoes.
- If you don’t have cider vinegar: Regular white vinegar is just fine.
- If you don’t have red onions: Yellow onions or scallions also taste great.
- If you don’t have honey: Use pure maple syrup.
As a Registered Dietitian, I absolutely love this recipe, especially for active women. It’s got a great blend of all three macronutrients – carbs, protein, and fat. The carbs provide energy for your workouts, the protein helps with muscle repair and recovery, and the fat helps with vitamin absorption and keeps you feeling full longer.
Right now, while many of us are perhaps not on the same fitness routine as a few months ago – it’s also nice that this is a calorie-controlled meal, clocking in right around 390 calories per serving. That’s helpful for any of us who are trying to manage weight (myself included!).
During the in-season, you can easily adjust the portion size to make it bigger for heavier training schedules that require higher calorie needs.
Lastly, this tuna potato salad is a good source several different vitamins and minerals. For example, you’re getting…
- 38% of your daily potassium needs, a key electrolyte lost in sweat that’s also involved in blood pressure regulation
- 47% of your daily Vitamin C needs, involved in immune function
- 19% of your daily iron needs, necessary for a healthy blood system that transports oxygen currently during exercise
- More than a day’s worth of Vitamin A, essential for eyesight
