canned diced tomatoes
tomato paste
garlic clove, minced
dried oregano
salt and black pepper
chili flakes (optional)

FAQs

Can I use any type of sardines?

Yes, any high-quality canned sardines in olive oil will work. Avoid those packed in tomato sauce for this recipe.

Do I need to debone the sardines?

Most canned sardines are soft-boned and edible as-is, but you can remove the backbone if preferred.

Can I make this in advance?

It’s best baked fresh, but you can prep the tomato mixture ahead of time to save a few minutes.

Can I use fresh tomatoes instead of canned?

Yes, finely chop and simmer them briefly to reduce liquid before mixing with the paste and spices.

Is this dish keto-friendly?

Yes, as long as you serve it with low-carb bread or vegetables instead of regular bread.

What other cheese can I use?

Try provolone, gouda, or feta for a twist on the classic mozzarella flavor.

Can I use the oven broiler instead?

Yes, broil for 2–3 minutes at the end to brown the cheese more deeply — just watch carefully to avoid burning.

What kind of bread works best?

Rustic sourdough, baguette slices, or any crusty bread that can scoop and hold the topping works well.

How do I reduce the saltiness?

Rinse the sardines lightly before using or balance with extra tomatoes and herbs.

Can I double the recipe?

Yes, just use a small baking dish instead of individual tins for a larger batch.

Sardine Margarita Bake is a warm, comforting dish that elevates humble ingredients into a gourmet-style experience. With its combination of rich sardines, melty cheese, and herbed tomato sauce, it’s the perfect blend of bold flavors and cozy simplicity.
