Is the Impossible Breakfast Sandwich Healthy?

Wondering about the health impacts of eating eggs daily? Our exploration of the surprising benefits of a week of daily egg consumption offers insights that might change how you view this breakfast staple.

This sandwich provides a good source of protein and iron thanks to its plant-based patty and eggs. It’s suitable for lacto-ovo vegetarians but not for vegans because it contains dairy and egg products. Here’s what stands out nutritionally:

  • Protein: At 21 g, it rivals many traditional meat-based sandwiches.
  • Fiber: Low at only 2 g per sandwich, so it’s less filling than some whole-grain options.
  • Saturated Fat & Sodium: Moderate to high; typical for most fast food sandwiches, but worth noting for those watching these nutrients.

For many, it strikes a reasonable balance between convenience, protein content, and reduced meat intake, but those watching sodium and cholesterol should choose mindfully.

Environmental Impact: Why Plant-Based?

Choosing plant-based options, such as the Impossible Sausage, can have a significant environmental benefit. Compared to traditional pork sausage, the Impossible patty produces fewer greenhouse gas emissions and uses less water and land in production. While Starbucks does not publish specific sustainability metrics for the full sandwich, the shift towards plant-based proteins aligns with growing consumer and corporate priorities for reducing food-related environmental impact.

  • Lower Greenhouse Gas Emissions: Plant-based meats generally contribute fewer emissions than animal meats.
  • Resource Efficiency: Using soy and other plant ingredients reduces the water and land needed per serving.
  • Animal Welfare: No direct animal slaughter is involved in producing the Impossible patty.

How Does It Taste?

If you’re wondering whether the Impossible Breakfast Sandwich delivers on flavor, here’s what most reviews consistently note:

  • Meaty, Savory Flavor: The soy leghemoglobin provides a distinctly meaty, umami-rich profile that mimics sausage well.
  • Cheesy and Satisfying: The cheddar cheese adds creaminess, while the ciabatta bun lends substance.
  • Eggy, Familiar Texture: The egg component is nearly indistinguishable from the standard Starbucks breakfast sandwiches.

In taste tests, even meat-eaters often appreciate the satisfying, savory flavor and texture of the Impossible patty. The biggest criticism is usually toward slightly higher sodium and the denser texture of the plant protein.
