Tuna Spaghetti in Slow Cooker

tuna spaghetti

Most kids love tuna and they love spaghetti, so why not to combine both in a slow cooker?! So, sugar free organic pasta sauce here you go on top of tuna spaghetti, sprinkled with green onions and freshly cracked black pepper. Maybe not so much pepper for the little ones.

This slow cooker spaghetti recipe is absolutely clean eating approved. We used pole and line yellowfin tuna packed in water which is more of a humane way used to fish for tuna as it doesn’t impact other marine life.

We wouldn’t recommend eating tuna too often due to its high mercury content and the fact that cans contain BPA, but on the night when you got absolutely no time or no food in the fridge make this tuna spaghetti.

This slow cooker recipe is a 3 hour recipe. So, you will either need to be home while tuna spaghetti is cooking or use slow cooker with a timer.

We realize it is not a true 8 hour slow cooker recipe but there is something magical about dumping everything in one pot and walking away for 3 hours. Hard to argue with that, right?! All ingredients (except green onions) come from the pantry. Doesn’t happen often when eating clean, right?!

We used whole wheat spaghetti and they came out full of absorbed sauce. Definitely not al dente but rather a creative mess in a bowl. Sometimes, isn’t the messiest and not the prettiest food the most comforting?! We could see a sprinkle of fresh grated cheese on top but that is up to you. Almost like a tuna pasta casserole. Enjoy!

Tuna Spaghetti in Slow Cooker




2 cups vegetable broth, low sodium
2 tsp garlic powder
10 oz whole wheat spaghetti
3 cans tuna, packed in water (with liquid)
Hot water (optional)
Ground black pepper, to taste
1/4 cup green onions, finely chopped


In a large slow cooker, add broth, pasta sauce, oil and garlic powder; stir to combine. Break spaghetti in half and fully submerge in sauce. Place tuna on top, breaking into pieces with a fork. Cover and cook on Low for 3 hours.
Turn off slow cooker. Depending on cooking time and type of spaghetti add hot water to thin out the sauce, if desired. We added about 1/2 cup. Sprinkle with green onions, ground black pepper to taste and gently stir. Adjust spices to taste. Serve warm.
