Step‑by‑Step Instructions for Creamy Crockpot Tuna Noodle Casserole

Step 1: Prepare Noodles
Begin by boiling a large pot of water over high heat. Add the egg noodles and cook according to the package instructions until they are al dente, usually about 6-8 minutes. Once cooked, drain the noodles and set them aside, allowing them to cool slightly while you prepare the sauce.

Step 2: Mix Sauce
In a separate mixing bowl, combine the cream cheese, milk, onion powder, garlic powder, salt, and pepper. Use a hand mixer or whisk to blend the ingredients together until you achieve a smooth and creamy consistency. This sauce will bind all the flavors together in your Crockpot Tuna Noodle Casserole.

Step 3: Combine Ingredients
In a large mixing bowl, gently fold the cooked egg noodles with the canned tuna and frozen peas. Pour the prepared sauce over the noodle mixture, and stir well until everything is evenly coated in that luscious, creamy goodness. Make sure no ingredient is left out, ensuring a fantastic flavor throughout.

Step 4: Transfer to Crockpot
Pour the combined mixture into a greased slow cooker, spreading it out evenly. Sprinkle an even layer of shredded cheese on top, which will melt during cooking and create a delicious, gooey topping for your Crockpot Tuna Noodle Casserole.

Step 5: Cook
Cover the slow cooker with its lid and set it to cook on low for 3-4 hours. As the casserole cooks, the flavors will meld together beautifully, and the cheese should melt into a blissfully creamy layer. You’ll know it’s done when the mixture is heated through and bubbling at the edges.

Step 6: Serve
Once cooked, remove the lid and gently stir the casserole to mix in the melted cheese. Serve it warm straight from the slow cooker, presenting a comforting bowl of creamy Crockpot Tuna Noodle Casserole that your family will love. Pair with a side salad or crusty bread for a delightful meal.
