How Long Does Tuna Noodle Casserole Last in the Fridge?

Tuna noodle casserole is a classic American dish that has been around for decades. This budget-friendly casserole is easy to make, holds well, and makes great leftovers. But how long will it last in the fridge before going bad?

As a busy home cook and mom, I’m always looking for ways to stretch my grocery budget and make meals that provide leftovers. Tuna noodle casserole checks all the boxes, and I love whipping it up for my family. However, I used to be unsure about how long it would stay fresh in the fridge. I wanted to avoid food waste but also didn’t want to serve up an unsafe meal.

After some research and trial and error I’ve got the scoop on exactly how long tuna noodle casserole lasts in the fridge. Follow these storage tips, and you’ll be able to safely enjoy leftover casserole for several days.

How to Store Leftover Tuna Noodle Casserole

The first step in maximizing your casserole’s fridge life is proper storage. Here are some tips

• Let the casserole cool completely before putting it in the fridge. You don’t want the steam to cause condensation that could lead to soggy noodles. Let it sit out for about 30 minutes after baking.

• Store in shallow airtight containers. The shallower the container, the faster the casserole will cool in the fridge. Airtight lids prevent fridge odors from seeping in.

• Don’t overpack containers. Leave some headspace so air can circulate and cool the casserole evenly.

• Refrigerate within 2 hours of cooking. Get your leftovers into the fridge while the temperature is still above 40°F.

• Label containers with the date. This helps you keep track of when it was made.

Following these steps will help block bacteria and maximize your casserole’s shelf life.

How Long Does Tuna Noodle Casserole Last in the Fridge?

With proper storage, tuna noodle casserole will keep well in the fridge for 3 to 5 days. I like to enjoy leftovers within 3 days for the best quality.

Here are some general fridge life guidelines:

• 3-4 days: Optimal quality, best taste and texture

• 5 days: Edible but noodles may be mushy, flavor fades

• 1 week: Increased risk of spoilage, toss it out

The exact timeframe depends on a few factors like the ingredients you used, how well you stored it, and your fridge temperature. Trust your senses. If it smells funky or has mold, it’s time to say goodbye!

Pro tip: Add a little extra milk or cream when reheating older casserole to combat dried out noodles.

Does Tuna Noodle Casserole Freeze Well?

Freezing is a great way to get even more mileage out of your tuna noodle casserole. It can last 2-3 months in the freezer with minimal quality loss.

To freeze:

• Let casserole cool completely, then divide into airtight freezer-safe containers. Leave 1-inch headspace for expansion.

• Label containers with contents and date.

• Freeze for up to 3 months.

To reheat frozen casserole:

• Thaw in the fridge overnight before reheating.

• Reheat gently in the oven or microwave until heated through, 165°F.

• Add a splash of milk and stir well if noodles seem dry.

With proper freezer storage, you can enjoy tuna noodle casserole even months later! It thaws beautifully.

Tips for Reheating Leftover Tuna Noodle Casserole

Here are some of my top reheating tips:

• Oven at 350°F: Bake in a covered dish 20-25 minutes until hot, stirring halfway.

• Microwave: Heat in 30 second bursts, stirring between until hot, 2-3 minutes.

• Add milk: For older leftovers, stir in 2-3 Tbsp milk before reheating.

• Avoid soggy noodles: Don’t overheat or the noodles will get mushy.

• Food safety: Heat to 165°F. Check temperature with a food thermometer.

Reheating gently, adding extra moisture, and using a thermometer are key for bringing leftover casserole back to life.

How Can You Tell if Tuna Noodle Casserole Has Gone Bad?

I rely on my senses to tell me when tuna noodle casserole has gone past its prime. Here are the signs it’s time to say bye-bye:

• Appearance: Mold growth, dried out noodles

• Texture: Extremely mushy or slimy noodles

• Smell: Sour, spoiled, funky odors

• Taste: Strong bitter, sour, or unpleasant flavors

• Past recommended fridge time: It’s been over 5 days in the fridge

When in doubt, remember the old adage – when in doubt, throw it out! Don’t risk food poisoning.
