Keto Dinner with Cottage Cheese and Fish Spread

A mix of regular and light cottage cheese, a thick fish spread, and crunchy vegetables creates a quick, protein-rich keto dinner, while a larger prepared batch of the spread simplifies a week of dinners or snacks.

Fish spread for several days

300 g well-drained light tuna in water, approximately 3 small cans
270 g well-drained sardines in olive oil, approximately 3 small cans
120 g homemade fermented cucumbers, well drained and roughly chopped
20 g full-fat Greek yogurt, approximately 1 heaped tablespoon
40 g onion, roughly chopped
10 g fresh chives
½ teaspoon freshly ground black pepper
1 teaspoon lemon juice, if needed

One dinner

100 g regular cottage cheese
100 g light cottage cheese
50 g homemade tuna–sardine spread
80 g celery stalks, cut into sticks

Method

Drain the fish thoroughly

Tip the tuna into a strainer and press it gently with a spoon. Drain the sardines, remove the skin, and leave the soft bones in place. Let the fish stand in the strainer for 5 minutes; less residual liquid means a thicker spread.

Remove excess moisture from the cucumbers

Roughly chop 120 g fermented cucumbers, then blot them or gently squeeze them with a clean kitchen towel. This prevents the spread from becoming watery overnight.

Blend the aromatic base first

Using a food processor and a few short pulses, finely chop 40 g onion, 10 g chives, and the cucumbers. Scrape the mixture down from the sides of the bowl.

Add the fish and yogurt

Add the drained tuna, sardines, 20 g Greek yogurt, and pepper. Pulse until the spread is thick and combined but not completely smooth. Overprocessing can turn the fish into a sticky paste.

Balance the flavor at the end

Taste the spread only after blending. The fermented cucumbers and canned fish are already salty, so additional salt is usually unnecessary. If the flavor is too heavy, add up to 1 teaspoon lemon juice; if the spread is too loose, chill it for 30 minutes.

Assemble the dinner

Mix 100 g regular cottage cheese with 100 g light cottage cheese. Add 50 g spread and 80 g celery sticks. Spoon the spread over the cottage cheese or only partially fold it in so the two textures remain distinct.

Why this combination works

◉

Two types of cottage cheese

The mixture preserves the flavor of the regular version and reduces energy density compared with using only full-fat cottage cheese.

🐟

Tuna and sardines

Tuna creates a lighter, firmer base, while sardines add a fuller flavor and fat. Their soft bones contribute calcium. [1]

◌

Fermented cucumbers and herbs

Acidity, onion, and chives balance the rich fish flavor. Add salt only after tasting.

🌿

Crunchy vegetables

Celery makes dipping possible without crackers and helps keep the dinner below 10 g net carbs.

✓

Choosing tuna

Choose canned light tuna for this recipe. The FDA lists sardines and light tuna among its lower-mercury choices; albacore, or white tuna, belongs to a different category. [2][3]

Variations for a different flavor and texture

For extra creaminess

Choose no more than one: 1 boiled egg (dinner stays below ~330 kcal), 15 g mayonnaise without added sugar (below ~360 kcal), 50 g avocado (below ~340 kcal), or 5 g olive oil (below ~305 kcal).

For dipping

Replace celery with 80 g cucumber, baby lettuce or radicchio leaves, a small amount of radishes, mini peppers, or raw zucchini. Adjust the quantity so net carbs remain below 10 g.

For a different flavor

Use capers, lemon zest, and dill; smoked paprika and cayenne; parsley, oregano, and lemon zest; sugar-free mustard; or spring onion instead of regular onion.

For more vegetables

Replace 50 g cottage cheese with one boiled egg and add cucumber, radishes, or zucchini. Always check the final combination against the actual product.

Frequently asked questions

Is the recipe keto?

Yes. Based on the unrounded calculation, one dinner contains less than 10 g total carbs and less than 10 g net carbs. Check the cottage cheese label.

Can I prepare dinner in advance?

Prepare the spread in advance, but portion the cottage cheese and vegetable sticks just before the meal.

Why is my spread too loose?

The most common reasons are insufficiently drained fish, wet fermented cucumbers, or too much yogurt.

Can I freeze the spread?

Freezing is not recommended because the yogurt, fish, and cucumbers may release water after thawing.

How long can I store it?

Keep it in a clean, airtight container at no more than 4 °C and use within 3–4 days.
