Ingredients for Your Slow Cooker Tuna Noodle Casserole
Gathering the ingredients for this easy tuna noodle casserole is a breeze. You’ll need:
- 1 (10.5 ounce) can condensed cream of mushroom soup
- 1 (10.5 ounce) can condensed cream of celery soup
- 1 (6 ounce) can tuna, drained and flaked
- 8 ounces egg noodles, uncooked
- 1 cup milk
- 1/2 cup shredded cheddar cheese
- 1/4 cup crushed potato chips (optional, for topping)
These simple pantry staples come together beautifully. The cream soups create a wonderfully rich sauce. Flaked tuna adds that classic flavor we all love. Uncooked egg noodles absorb all that deliciousness as they cook. It’s truly a straightforward list.

Ingredient Notes and Substitutions
For a richer, more decadent flavor, I always reach for whole milk. It really makes a difference! If you want to sneak in some extra goodness, a cup of frozen peas or corn is a fantastic addition. Just stir them in with the other ingredients. Don’t have cream of mushroom soup? A second can of cream of celery soup works well. Or, you could try cream of chicken soup. Just ensure they are condensed versions for the right consistency.
How to Make Slow Cooker Tuna Noodle Casserole: Step-by-Step
Making this easy tuna noodle casserole is a dream, seriously. It’s so simple, you’ll wonder why you ever bothered with the stovetop version. Let’s get this comforting meal going!
Combining the Ingredients
First, grab your slow cooker. Into the insert go the cream of mushroom soup and cream of celery soup. Then add your drained and flaked tuna. Toss in the uncooked egg noodles next. Pour in the milk. Give it all a good stir. You want everything nicely combined. It’s that simple for the first step!
Cooking to Perfection
Cover your slow cooker. Set it to low heat. Let it cook for about 2 to 3 hours. Keep an eye on those noodles; you want them tender. If you can, give it a stir now and then. Every slow cooker is a little different. So, your cooking time might vary slightly. Just make sure it’s all heated through. That’s key!

Adding the Finishing Touches
About 15 minutes before you’re ready to serve, stir in the shredded cheddar cheese. Let it melt into the casserole. Oh, that creamy goodness! If you like a little crunch, sprinkle the crushed potato chips over the top right before serving. It adds a fun texture. Now it’s ready to eat!
Tips for the Best Slow Cooker Tuna Noodle Casserole
To make sure your slow cooker tuna noodle casserole turns out amazing every time, a few little tricks help. For super tender noodles, don’t overcook it. The 2-3 hour window on low is usually perfect. Stirring occasionally, if you can, helps everything cook evenly. This is Savana Loyal’s secret: making it taste like you fussed all day. Keep an eye on liquid levels too; if it seems too thick, a tiny splash more milk works wonders. This simple approach guarantees a delicious, comforting meal.
Serving Suggestions for Your Comforting Casserole
This hearty slow cooker tuna noodle casserole is a meal in itself! But if you’re looking to round out your dinner, I love serving it with a simple green salad. A crisp side salad with a light vinaigrette cuts through the richness beautifully. Steamed broccoli or green beans also make a wonderful addition. For that true family recipe feel, a side of buttered dinner rolls is always a hit. They’re perfect for soaking up any extra creamy sauce!
Storage and Reheating Instructions
Leftovers of your delicious slow cooker tuna noodle casserole store beautifully. Once cooled, transfer any remaining portions to an airtight container. It will keep well in the refrigerator for up to three days. To reheat, I find the microwave works best for a quick fix. Just a minute or two, stirring halfway through, usually does the trick. For a more evenly heated dish, you can gently warm it in a low oven, around 300°F (150°C), covered, until heated through.
Frequently Asked Questions about Slow Cooker Tuna Noodle Casserole
Got questions about this easy tuna noodle casserole? I’ve got answers!
Can I use fresh noodles? Fresh egg noodles cook much faster. I’d suggest adding them in the last 30-45 minutes of cooking. This prevents them from getting mushy. Stick to the uncooked dried noodles for the best hands-off result.
What if I don’t have cream of mushroom soup? No worries! You can easily substitute it with another can of condensed cream of celery soup. Cream of chicken soup also works well. Just make sure it’s condensed for the right creamy texture.
How can I make this a vegetarian tuna noodle casserole? To make this a vegetarian comfort food delight, simply omit the tuna. You can add extra vegetables like peas, carrots, or corn for heartiness. Some people even add a can of drained chickpeas for a protein boost. It’s still wonderfully savory and satisfying!
