🥘 Sardine Bake Ingredients
Here’s what you need to make baked canned sardines:
- Canned smoked sardines
- Yellow potatoes
- Yellow onion
- Garlic cloves
- Carrots
- Olive oil
- Cherry tomatoes
- Fresh lemon juice
- Lemon zest
- Crushed red pepper (optional)
- Salt (optional)
As always, find the specific quantities of ingredients in the recipe card at the bottom of the post!
Use a potato with a thin skin for this recipe so no peeling is needed. You can use fingerlings, little potatoes, or larger ones. I went with little potato niblets to minimize the amount of chopping I need to do.
Roma tomatoes are fine here instead of cherry tomatoes. Just make sure to dice them up!
This recipe calls for optional red pepper flakes, but feel free to make substitutions as you feel appropriate. Add cayenne for even more heat, or some paprika or garlic powder for a different twist on the flavor.
Remember to add spices gradually. You can always add more right before serving, so it’s seasoned to individual tastes.
To make this recipe, you also need a good knife and a baking dish. I use this 2.5-quart oval ceramic casserole dish for this recipe. I don’t recommend using a metal baking pan, as it will alter the cooking time.
🔪 How to Bake Canned Sardines
Rinse the potatoes and chop them into ½-1 inch dice (1.27-2.54 cm). Chop the carrots and onion into ½ inch dice (1.27 cm). Peel and mince the garlic and halve the small cherry tomatoes.
Preheat the oven to 450F (232C). Mix the potatoes, onion, carrots, tomatoes, garlic, red pepper (if using), lemon juice, and olive oil. Mix in the zest. Season with salt if needed.
Put the mixture in a casserole dish and place on a rack ⅓ down from the top of the oven. Bake uncovered for 40-45 minutes, until the potatoes are tender.
Drain the canned sardines and place them on top of the veggies. Put the casserole baking dish back in the oven.
️⏲️ Cooking Time and Temperature
How long to oven bake canned sardines? What temperature to oven bake canned sardines? Roast canned sardines for 3-5 minutes at 450 degrees Fahrenheit (232C). (This is the cooking time for the sardines after the veggies have been baking 40-45 minutes.)
Remove your sardine bake from the oven and let cool several minutes before serving. Enjoy!
️🌡️ Canned Baked Sardines Leftovers
You can keep leftover sardine bake in a covered container in the fridge for 1-2 days. Microwave individual servings for 2-3 minutes on high to reheat.
I don’t recommend freezing leftovers as the potatoes in this dish don’t freeze well.

💭 Expert Tips from a Dietitian
This is a level 1 recipe (may help support fat loss). What are the benefits of eating sardines for weight loss purposes? Here are a few:
- High in protein to help keep you full
- When paired with veggies (such as here) gives you a low calorie and high volume meal
- Not specifically weight-related, but it’s an oily fish, so you’re getting more omega-3s than from some other fish varieties
So, are sardines healthier than tuna? I would include both in the diet if you enjoy them, but sardines provide more omega-3s. In general, I would consider sardines to be the more nutritious choice between the two.
Another common question is: can you eat sardines every day? While it’s true that sardines are a small, low mercury fish, I’d stick to enjoying them 2-3 times per week. That leaves plenty of room in your diet for a variety of other nutritious protein sources.
My philosophy is that it’s wise to think of your overall diet like an investment portfolio. By diversifying (eating a variety of foods from different food groups), you help ensure you’re getting the full range of nutrients your body needs. The more you limit your healthy food choices, the greater the risk of nutrient deficiencies and other health issues.
Anyhow, back to the sardine bake. This is a wonderful meal for a light dinner or a lunch prep if you’re looking to eat healthier.
Make this sardine bake in the evening, and lunch will be ready for the next day or two. All you have to do is reheat and eat! (So delicious and easy!)
FAQs
What are the best canned sardines?
I recommend finding sardines tinned with the bones and packed in olive oil for this recipe. The bones are a great non-dairy source of calcium and olive oil provides an extra layer of flavor in this dish. The last time I made this recipe, I used Wild Planet Brand sardines, which are available at Costco and on Amazon.
Where to find BPA-free canned sardines?
Several canned sardine brands are BPA-NI, meaning BPA is not intentionally added to packaging. Wild Planet Brand and Season sardines are two options.
How to make canned sardine bake keto?
You can make a low carb sardine bake by substituting the potatoes in this recipe for chopped cauliflower. This swap will also make your canned sardine bake Paleo diet friendly.
Should you eat the oil in sardines?
Some chefs recommend discarding the oil in canned sardines because it tends to be lower quality. I say save your money and use the oil! Canned sardine oil is often rich in omega-3 fatty acids from the fish. It can be used in a wide variety of cooking applications, including making salad dressings.
Can I eat sardines straight from the can?
Like canned tuna, tinned sardines are fully cooked and can be eaten from the can. If you can find canned sardines in tomato sauce and seasonings, that tends to be tastier than eating plain sardines.
How to cook sardines without smell?
Sardines should have only a mildly fishy odor. Very strong and unpleasant smells can indicate that the fish has gone bad and needs to be thrown out. Cooking fish in flavored liquids (such as broths or a tomato sauce) can help mask the smell. You could also grill the fish outside if the smell tends to bother you.

I will try this recipe with salmon as my girls prefer salmon over any other fish.
Thanks for also giving the veg fried rice and the salad recipe to go with this and anyday chickpeas top the list with me. Thanks
Summer Yule says
That is so terrific that they like salmon! Salmon is a great one to substitute for the sardines since it's another omega-3 rich fatty fish. I hope your family enjoys this recipe! 🙂
Terrified Amateur says
To be honest, I never equated canned fish with elevated cuisine. Yes, my thinking went, it offers convenience, but is far too oily and salty to do anything but overwhelm whatever accompanies it.
Recently, though, opinions began to soften. The first reconsideration came courtesy of Spain, or at least Spanish canned seafood, most of which is sublime. To be fair, though, pricey too.
The second breech? Why, this entry, Summer! If treated, intelligently, as fish are in this case, they can be a healthy and delicious alternative. Leave it to you to shine the light in a promising and unexpected new direction, Summer1
Summer Yule says
Aww, thanks! I have also experienced the high-quality canned offerings in other countries. You can purchase canned duck confit in France for what would be $8-10 here. It's far more than most U.S. canned goods but what you get for your purchase is beyond divine. Perfectly prepared duck packed in fat that can be used to roast baby potatoes. Amazing!
In fact, the duck confit was so good that I ordered a large can to enjoy one Valentine's Day. I'm not sure that there are any canned goods in the U.S. that I would use as the main dish in a holiday meal. The downside was that my duck confit cost far, far more than the $8-10 I would have paid in France.
There are also some very high-quality canned cod livers available in Scandinavian countries. That's another item I have ordered online. I definitely agree that there are many excellent canned products available worldwide! I think the tinned fish we have here is a good start. Hopefully, our local selection of canned goods will one day rival what you can get in France. I can dream. Haha
