Tuna pasta with red onion

Tuna paste with red onion When I need something quick for sandwiches, tuna paste with red onion is one of the simple options I turn to. It is prepared by mixing a few ingredients, and the onion added at the end keeps the texture and fresh taste. The paste is spread on toasted bread and can be served for breakfast, as a snack, or at a cold meal. The recipe does not require actual cooking, just a little time for preparing the ingredients. Quick info Total time: the exact time is not specified in the source recipe; preparation is quick Preparation time: not specified Cooking or baking time: not necessary for the paste Servings: the number of servings is not specified; the amount is sufficient for sandwiches, depending on how generously the paste is spread Difficulty: easy Recipe type: appetizer, cold snack, sandwiches Ingredients 1 can of tuna in olive oil, 160 g 1 teaspoon of mustard 1/4 pack of soft butter 1 teaspoon of lemon juice A pinch of salt, to taste 1 red onion Slices of toasted bread, for serving The butter should be soft before mixing, so it combines more easily with the tuna. The red onion is finely chopped and added after the base paste is homogenized. This way, the onion remains visible in the mixture and provides a more pronounced flavor. Preparation method 1. Put the soft butter, tuna, lemon juice, and mustard in a blender. 2. Blend the ingredients until you get a homogeneous mixture. If needed, stop the blender and scrape the mixture from the sides, then continue blending until the ingredients are well incorporated. 3. Taste the paste and add a little salt. The tuna and mustard already have flavor, so it's better to start with a small amount. 4. Finely chop the red onion and add it to the tuna paste. 5. Mix to evenly distribute the onion. In the basic recipe, the onion is added after blending the tuna, not blended together with the other ingredients. 6. Spread the paste on slices of toasted bread and serve. The toasted bread can be prepared while the paste is being blended. It is important that the butter is soft, not hard, as cold butter is harder to homogenize in the blender. The onion should be finely chopped, but it doesn't need to be turned into a paste. Why I make the recipe often Tuna paste with red onion is easy to prepare and uses few ingredients. No cooking is required, and most of the preparation consists of blending the ingredients and chopping the onion. The flavor can be easily adjusted with salt, lemon, and mustard, without the need for other spices. It is especially useful when I want sandwiches prepared quickly. The base of tuna and butter has a creamy texture, while the red onion adds contrast and a more intense flavor. The recipe can be kept in paste form and spread on bread at the time of serving, but the source does not specify an exact storage time. Tips Use soft butter, as it combines more easily with the tuna in the blender. If the butter is hard, the mixture may remain uneven. Add salt gradually. The tuna in oil and mustard may already be salty enough, depending on the brand used. Finely chop the red onion. Large pieces feel unpleasant on the sandwich and are harder to distribute in the paste. The onion is added after blending. If it is put in the blender from the start, the final texture will be different from that of the original recipe. The lemon juice is used in a small amount but helps balance the flavor of the butter and tuna. Substitutions The source recipe does not indicate direct substitutes for tuna, butter, mustard, or red onion. To maintain the flavor and texture of the recipe, it is recommended to stick to the basic ingredients. Toasted bread is the recommended base for serving. The quantity and type of slices are not specified, so they can be chosen according to preference and how much paste is produced. Variations For a different variation, avocado, smoked salmon, boiled egg yolk, or turmeric can be added to the tuna paste. These are suggestions from the original recipe and can change both the flavor and texture of the dish. Avocado can make the mixture creamier. Smoked salmon will bring a more intense fish flavor, while boiled egg yolk will thicken the paste. Turmeric mainly changes the aroma and color. The source does not specify quantities for these additions, so it's better to use them sparingly, to taste. Serving ideas The paste is served on slices of toasted bread, as sandwiches. It is suitable for a quick breakfast, a snack, or a cold platter. It can be spread directly on bread after preparation. If prepared in advance, keep the paste separate and put it on the bread close to serving time, so the slices retain their crunchy texture. Frequently asked questions 1. Do I drain the oil from the tuna can? The recipe indicates tuna in olive oil and does not mention draining the oil. Follow the original instructions and put the tuna in the blender along with the other ingredients, without adding or removing a step that is not mentioned. 2. Can I use white onion instead of red onion? The recipe is made with red onion, which has specific taste and color. The source does not provide substitutes, so for the original result, it is advisable to use red onion. 3. What do I do if the paste does not homogenize at first? Check if the butter is soft enough and continue blending. You can stop the blender to gather the mixture from the sides, then blend again. The onion should not be blended at this stage; it is added after obtaining the tuna paste. 4. Can I add the onion directly to the blender? In the original recipe, the red onion is finely chopped and added after the tuna, butter, lemon, and mustard have been homogenized. Following this step keeps the pieces of onion in the mixture. Nutritional values The values are estimates and do not include the slices of toasted bread, as the quantity of bread is not specified. Additionally, the values may vary depending on the brand of tuna, the exact amount of butter in a package, and how much oil is in the can. For the entire amount of paste, the estimate is approximately 650-850 kcal, 35-45 g protein, 45-60 g fat, and 8-15 g carbohydrates. If the paste is divided into several sandwiches, the values per serving depend on the number of slices and the amount spread on each. Toasted bread should be calculated separately, as it adds extra calories and carbohydrates. There is not enough information in the recipe for an exact estimate per serving. Storage and reheating The tuna paste is served cold or at room temperature and is not a dish that requires reheating. The source recipe does not specify how long it can be stored, so it is preferable to consume it fresh and not make it in larger quantities than necessary. If prepared ahead of serving, keep the paste separate from the toasted bread. The bread slice will become soggy if spread too far in advance. Freezing is not recommended, as the mixture contains butter and ingredients with textures that may change after thawing.
