Tuna casserole is a classic comfort food loved by many for its simplicity and versatility. Whether you’re preparing a cozy family dinner or looking to use up pantry staples, canned tuna offers a quick and affordable solution. But when it comes to choosing between tuna packed in water and tuna packed in oil, which one is better for your casserole? The answer depends on a few factors, including flavor preferences, health considerations, and the type of casserole you’re making.
In this guide, we’ll explore the differences between these two types of tuna and help you make an informed decision about which one is best for your next casserole dish.
The History of Tuna in Casseroles
The tradition of using tuna in casseroles dates back to the 1950s in the United States, a time when canned goods and pantry staples were the backbone of home-cooked meals. Canned tuna became widely available after World War II and quickly gained popularity due to its affordability and long shelf life. The classic tuna noodle casserole—made with canned tuna, noodles, and cream-based soups—became a staple in American households.
During this time, many recipes called for tuna packed in oil, as it was considered more flavorful and indulgent. However, as dietary preferences shifted toward lower-fat and healthier options in the following decades, tuna packed in water became more common in casserole recipes. Today, both types of tuna are widely used, each offering its unique benefits depending on the dish you’re preparing.
Nutritional Comparison: Tuna in Water vs. Tuna in Oil
Canned tuna, regardless of whether it’s packed in water or oil, is a fantastic source of protein, omega-3 fatty acids, and essential vitamins and minerals. However, the liquid it’s packed in can affect its caloric and fat content.
| Nutritional Factor | Tuna in Water | Tuna in Oil |
|---|---|---|
| Calories | Lower (90-100 kcal per serving) | Higher (160-200 kcal per serving) |
| Fat Content | Minimal (0.5g) | Higher (5-10g) |
| Omega-3 Fatty Acids | Present | Higher absorption due to oil |
| Moisture Retention | Lower | Higher |
| Protein | High (20-25g per serving) | High (20-25g per serving) |
Health Benefits of Tuna
Both tuna in water and tuna in oil offer a variety of health benefits:
- Rich in Protein: Tuna is an excellent source of lean protein, which helps build and repair muscles, supports immune function, and provides lasting energy.
- Omega-3 Fatty Acids: Omega-3s are essential for brain health, reducing inflammation, and supporting heart health. While tuna in oil may have slightly more absorbable omega-3s, tuna in water still provides a significant amount.
- Low in Mercury: Canned tuna, particularly light tuna, tends to have lower mercury levels compared to fresh or larger species of fish like swordfish or shark. This makes it a safe and nutritious option for most people, though pregnant women and young children should monitor their intake.

Flavor Profile: How Each Affects the Casserole
The type of tuna you use can significantly impact the flavor of your casserole. Here’s a breakdown of how tuna in water and tuna in oil perform in terms of taste.
Tuna in Water
Tuna packed in water has a clean, mild flavor that allows the other ingredients in your casserole to take center stage. This makes it an ideal choice for casseroles that feature strong flavors or rich sauces, as the tuna won’t overpower the other components of the dish. However, some people find that tuna in water can be too bland on its own and may need additional seasoning to enhance the flavor.
- Best for casseroles with bold flavors, such as those with cheese, garlic, or herbs.
- Provides a lighter taste, making it suitable for low-fat or low-calorie casseroles.
Tuna in Oil
Tuna packed in oil is richer and more flavorful due to the fat content of the oil. The oil helps retain the natural flavors of the tuna, giving it a more robust and indulgent taste. This makes it an excellent choice for casseroles where the tuna is a key ingredient and you want its flavor to stand out.
- Adds a layer of richness to your casserole, making it perfect for creamy or cheesy dishes.
- Retains more moisture, preventing the tuna from drying out during baking.
For a richer dish where the tuna flavor needs to shine, consider using oil-packed tuna in a hearty casserole like the one paired with potato chips, which you can explore here.
Texture Considerations: Tuna in Water vs. Tuna in Oil
The texture of the tuna also varies depending on whether it’s packed in water or oil. This can affect how the tuna behaves in your casserole, particularly during baking.
Tuna in Water
Tuna in water tends to have a flakier, drier texture compared to oil-packed tuna. While this is a good option if you’re aiming for a lighter dish, it can sometimes make the tuna dry out during the cooking process. To combat this, you may want to use additional moist ingredients like a cream-based sauce or extra cheese to maintain moisture in the casserole.
- Flaky texture that can blend well with other ingredients, but may require more sauce to stay moist.
- Ideal for casseroles where you want a lighter, less greasy texture.
Tuna in Oil
Tuna in oil retains more moisture due to the oil, resulting in a softer, more tender texture. This makes it a great choice for casseroles that require long baking times or are rich in dry ingredients like pasta or breadcrumbs. The oil helps the tuna stay juicy and prevents it from becoming too dry.
- Moist and tender texture, perfect for casseroles that require a longer baking time.
- Ideal for creamy or cheesy casseroles, where the oil helps maintain a luxurious mouthfeel.

Cooking and Baking Performance
How Each Tuna Holds Up During Cooking
Tuna in water and tuna in oil react differently to heat and cooking, so it’s important to consider how they will perform in your casserole.
- Tuna in Water: Tends to dry out more quickly, especially during extended baking times. If you’re using water-packed tuna, it’s a good idea to add extra moisture to the dish, such as a cream sauce, broth, or cheese.
- Tuna in Oil: Retains its moisture better during cooking, making it less likely to dry out. The oil helps keep the tuna tender and adds richness to the dish.
Which Tuna Works Best for Specific Casseroles?
The type of tuna you choose should align with the kind of casserole you’re preparing. Here’s a guide to help you decide:
- Tuna in Water: Works best in lighter casseroles that focus on fresh vegetables, herbs, and lean proteins. It’s also ideal for dishes where the tuna is meant to complement, rather than dominate, the flavor profile. Consider using water-packed tuna in casseroles like lemon and blueberry chicken where the emphasis is on a clean, fresh taste. You can find a similar recipe here.
- Tuna in Oil: Best for indulgent casseroles that feature rich sauces, cheese, and pasta. The oil adds a layer of luxury to the dish and helps the tuna maintain its texture and moisture during baking.
Health Implications of Tuna in Water vs. Tuna in Oil
The type of tuna you use can also affect the healthfulness of your dish. While both types of tuna offer excellent nutritional benefits, there are key differences in their fat and calorie content.
Tuna in Water
Tuna in water is the healthier option for those looking to reduce fat and calorie intake. Because it’s packed in water rather than oil, it contains fewer calories and virtually no added fat. This makes it ideal for people following a low-fat or calorie-controlled diet.
- Low in Calories: With only around 90-100 calories per serving, tuna in water is a great choice for lighter casseroles.
- Minimal Fat: Since the tuna is packed in water, there’s little to no added fat, making it a healthier option for those looking to reduce their fat intake.
Tuna in Oil
Tuna in oil is higher in fat and calories, but it also contains heart-healthy omega-3 fatty acids. These healthy fats have been shown to support heart health, reduce inflammation, and improve brain function. However, it’s important to be mindful of the extra calories that come with the oil.
- Higher in Calories: Tuna packed in oil contains around 160-200 calories per serving, making it a more indulgent option.
- Contains Healthy Fats: The oil helps preserve omega-3 fatty acids, which are beneficial for heart and brain health. However, it’s important to drain the tuna thoroughly to avoid adding too much oil to your casserole.

Yes, you can mix the two types of tuna if you want a balance of flavor and texture. This is a great way to enjoy the richness of oil-packed tuna without making the dish too heavy. Just make sure to drain both cans before adding them to your casserole.
Q: Does using tuna in oil make the casserole too greasy?
Not necessarily, as long as you drain the tuna properly. The oil-packed tuna will add more moisture and flavor to the dish, but draining off the excess oil will prevent the casserole from becoming too greasy.
Q: Is tuna in oil healthier than tuna in water?
Tuna in water is generally considered the healthier option due to its lower fat and calorie content. However, tuna in oil contains heart-healthy fats, which can be beneficial if consumed in moderation. It’s all about balance—if you’re making an indulgent dish, tuna in oil is a great option. If you’re watching your calorie intake, go with tuna in water.
Conclusion: Which Tuna Should You Choose?
When it comes to choosing between tuna in water and tuna in oil for casseroles, it really depends on your personal preferences and the type of dish you’re making.
