How much protein is in one streaky bacon?

November 25, 2025 •

3 min read

According to USDA data, a single slice of cooked streaky bacon contains approximately 2 to 3 grams of protein. While often enjoyed for its rich flavor and crispy texture, bacon is actually much higher in fat than it is in protein. Understanding the precise protein content in one streaky bacon slice is key for those tracking their macronutrient intake.

Quick Summary

This article details the protein content of a single streaky bacon slice, exploring how variables like slice thickness, cooking method, and specific brand can influence the final nutritional value. It also compares streaky bacon's protein levels to other breakfast meats and discusses its role in a balanced diet.

Key Points

Low Protein Content: A single slice of cooked streaky bacon contains only 2 to 3 grams of protein.
High in Fat: Streaky bacon is significantly higher in fat than in protein, making it less ideal as a primary protein source.
Cooking Method Matters: Cooking methods that drain fat, like baking on a rack, can reduce fat content, but the protein amount per slice remains stable.
Alternative Options: Leaner alternatives like Canadian bacon offer significantly more protein per slice.
Moderation is Key: Due to high sodium and saturated fat, streaky bacon should be consumed in moderation and paired with other protein-rich foods.
Brand Variation: Slice thickness and brand-specific curing can cause slight variations in the protein content.
Flavor Over Function: Bacon's main dietary contribution is its flavor and texture, not its protein content.
Balanced Breakfast: Pairing bacon with other protein sources like eggs ensures a more complete, protein-rich meal.

Streaky Bacon's Protein Content Explained

The protein content in a single slice of streaky bacon is not a one-size-fits-all number. While official data from sources like the USDA provide an excellent baseline, several factors can influence the final amount. On average, a standard, cooked slice of streaky bacon contains roughly 2 to 3 grams of protein. This modest amount often surprises people, as bacon is more commonly associated with its higher fat and sodium content.

Factors Influencing Protein in Streaky Bacon

Slice Thickness: Thicker-cut bacon will naturally contain more overall mass, including more protein, per slice than thinner-cut versions. A single 'thick' slice might have closer to 4-5 grams of protein, while a 'thin' slice could be on the lower end of the 2-3 gram range.
Cooking Method: How you cook your bacon significantly impacts the fat content, but the protein remains relatively stable, though some minor losses can occur. For example, baking bacon on a rack or draining off excess grease after pan-frying will reduce the overall fat, but the protein count per slice will be largely unaffected.
Brand and Curing: Different brands may use varying curing processes and cuts, leading to slight nutritional differences. Checking the specific nutrition label on the package is the most accurate way to determine the protein content for your chosen brand.

Streaky Bacon vs. Other Breakfast Meats

When considering protein sources for breakfast, it's helpful to compare streaky bacon to other popular options. This table highlights how streaky bacon's protein compares on a per-slice or per-serving basis.


Meat Type	Typical Protein per Slice/Serving	Key Nutritional Differences
Streaky Bacon	~2-3 grams per cooked slice	Highest in fat, distinct meat-fat layering.
Canadian Bacon	~5-6 grams per slice	Much leaner, less fat, higher protein density.
Turkey Bacon	~2-3 grams per cooked slice	Lower in fat and calories compared to pork streaky bacon.
Breakfast Sausage	Variable, but often higher than streaky bacon	Can vary significantly by brand and type (patties or links).

The Role of Streaky Bacon in a Balanced Diet

While streaky bacon may not be the most protein-dense breakfast food, it can still play a role in a balanced diet. It's best to view it as a flavoring component rather than a primary source of protein. For example, pairing a few slices of bacon with other protein-rich foods like eggs, Greek yogurt, or nuts will ensure you meet your daily protein targets.

Incorporating bacon can also help boost satiety due to its fat content, which can be beneficial for those on low-carb diets like keto. However, due to its high sodium and saturated fat levels, moderation is crucial. For those monitoring sodium or fat intake, choosing leaner bacon alternatives or simply using smaller quantities is a healthier approach.

Maximizing Protein from Your Meals

For a protein-focused breakfast, it is wise to add other components. Consider a platter that includes:

Two eggs, scrambled or fried, adding approximately 12 grams of high-quality protein.
A side of Greek yogurt or cottage cheese for an additional protein boost.
Avocado, which adds healthy fats and a creamy texture.
A small portion of streaky bacon to add flavor and a crispy texture without relying on it for the bulk of your protein intake.

This method allows you to enjoy the flavor of streaky bacon while still building a nutritionally complete and satisfying meal. For those interested in leaner pork options, opting for back bacon from the loin can provide a meatier, higher-protein slice. For example, two rashers of back bacon can offer significantly more protein than two slices of streaky.

Conclusion

To sum up, while delicious, streaky bacon offers a relatively small amount of protein—just 2 to 3 grams per cooked slice. Its nutritional profile is dominated by fat and sodium, making it a flavor enhancer rather than a primary protein source. Understanding this is key to fitting it into a balanced diet, perhaps by pairing it with other protein-rich foods or opting for leaner bacon alternatives like Canadian bacon. By keeping an eye on serving sizes and combining it with other healthy choices, you can enjoy your favorite breakfast food responsibly.

Frequently Asked Questions

Since a single slice contains only 2 to 3 grams of protein, you would need to consume several slices of streaky bacon to make a substantial contribution to your daily protein intake. For instance, four to five slices might provide around 10-15 grams of protein, but this would also add a significant amount of fat and sodium.

No, streaky bacon is not considered a good source of protein for muscle building due to its low protein-to-fat ratio. Protein-dense foods like chicken breast, lean beef, or eggs are far more effective for this purpose.

Back bacon, which is cut from the leaner pork loin, contains significantly more protein and less fat than streaky bacon, which comes from the fattier pork belly. Canadian bacon is an example of a very lean, high-protein bacon alternative.

Cooking bacon does not significantly change its protein content. The primary nutritional change comes from the rendering of fat, which reduces the overall fat calories in the final product.

Yes, streaky bacon can be a small part of a high-protein diet, but it should not be the main source. It is best used as a flavouring component to complement other, more protein-rich foods.

The curing process itself has minimal impact on the final protein content. Curing primarily adds flavour and preservatives, while the protein amount is largely determined by the initial cut of meat.

To make a high-protein breakfast, combine a small portion of streaky bacon with other protein sources. For example, serve one or two slices alongside scrambled eggs and a side of cottage cheese or a protein smoothie.
