There’s nothing wrong with including bread in a balanced diet. In fact, it can be a delicious and nutrient-dense element of any meal.

But if you are trying to limit carbs to manage your blood sugar or following a gluten-free, keto, or paleo diet, you may be searching for ways to replace bread in your diet.

With popular sandwiches like chicken salad, egg salad, roast beef, or club sandwiches available almost anywhere, sometimes low-carb options can be hard to find. Luckily, when it comes to no-bread sandwiches, there are plenty of options to choose from to add a creative flair to your favorite classic.

Let’s take a look at what goes into a no-bread sandwich and some low-carb sandwich alternatives to try!

What to Consider When Building a Healthy Sandwich

Typically, there are at least three elements that make up a traditional sandwich: the bread, filling, and spread.

In a typical sandwich, the outer bread layer is a carb, like bread, a bun, or a tortilla. The filling is usually made up of a source of protein and vegetables. Finally, the spread is usually something creamy such as ketchup, mustard, hummus, or mayonnaise to add flavor.

Before we get into some of the best no-bread alternatives, let’s cover the best fillings and condiments to include in your healthy sandwich.

Sandwich Fillings

Sandwich filling with eggs, avocado, corn

Sandwiches are a great way to a variety of nutrient-dense foods into your diet. Adding a lean protein source is a great way to make your sandwich more satiating and support a better blood sugar response.

The Dietary Guidelines for Americans also suggests that half of each meal is made up of fruits and vegetables, and recommends limiting sodium, added sugars, and saturated fats.

Including a mix of different vegetables (or even fruits) inside your sandwich can help add flavor and also boost the vitamin, mineral, and fiber content of your meal.

With these guidelines in mind, consider filling your sandwich with some of the following options:

  • Fatty fish that contains omega-3 fatty acids, like tuna, sardines, or salmon
  • Veggies or fruits, like cucumber, apples, tomato, bell peppers, onions, avocado, or lettuce leaves
  • Lean proteins such as eggs, sliced turkey, grilled chicken breasts, sliced tofu or tempeh, and turkey burgers


Aside from adding flavor and texture, condiments can also provide nutrients. Consider adding:

  • Mustard, which often contains turmeric, a spice that is high in antioxidants.
  • Tahini, a paste made from sesame seeds, which may have a positive effect on blood sugar.
  • Hummus, a popular dip made from chickpeas, which may decrease your risk of heart disease, type 2 diabetes, and obesity.
  • Nut butter, which may lower your risk of cardiovascular disease.
  • Kimchi or sauerkraut, two forms of fermented cabbage, which are full of antioxidants and probiotics which may have a positive effect on your gut
  • Red hot sauce made from chili peppers, which may have anti-inflammatory and analgesic properties.

Consider these Creative Low-Carb Bread Alternatives

No matter what fillings and condiments you choose for your breadless sandwich, there are lots of creative ways to pack all the ingredients together. Here are a few healthy alternatives plus easy no-bread sandwich recipes to try!


Lettuce wrap with bacon, avocado, peppers

Lettuce is a very popular bread alternative, and you may even find romaine lettuce wraps as an option at restaurants as a low-carb option.

Lettuce wraps are easy to hold and low in fat and carbs (but rich in vitamins and minerals), making it an ideal option for recreating a classic sandwich, like a BLT. Bibb lettuce, for example, is rich in vitamin A — a head of it contains 108 percent of your daily recommended value.

Vitamin A is crucial for many functions in your body, including the immune system, your vision, and growth and development. Vitamin A deficiency has even been associated with an increased risk of cancer.

  • Leaves from one medium head of butter lettuce
  • 6 slices bacon (about 6 ounces)
  • 2 tablespoons mayonnaise
  • 1 tablespoon finely chopped chives
  • 1 tablespoon freshly squeezed lemon juice
  • ⅛ teaspoon freshly ground black pepper
  • 1 pint cherry or grape tomatoes, halved
  • 1 medium avocado, diced

Portobello Mushrooms

You may know that portobello mushrooms can be used as an alternative to meat in a sandwich, but did you know they’re also great substitutes for bread?

Portobello mushrooms are thick and meaty, making them a great option for holding a sandwich together. They’re also full of antioxidants, which protect your cells from damage-causing free radicals, and beta-glucans.

These polysaccharides are found in mushrooms and have been shown to have anti-carcinogenic effects, stimulate the immune system, and may even have a positive effect on blood sugar.

  • 4 tablespoons tzatziki

Bell Peppers

Bell peppers make a great bread alternative for a sandwich. These veggies are firm and hollow, and can even be stuffed with whatever filling you choose. One red bell pepper contains 67 percent of your daily recommended dose of vitamin A, and a whopping 325 percent of your daily recommended vitamin C.

Vitamin C is required for the production of collagen, which is a crucial component of the connective tissue that is important for wound healing. It also supports immune system function and may also play a role in regulating blood sugar and blood pressure.

Bell peppers themselves also contain antioxidants that may have a positive effect on cholesterol.

Cucumbers can add a great, crunchy texture to a no-bread sandwich. Cucumber may have a positive effect on diabetes and cholesterol, and its seeds are known to prevent constipation.

Cucumber contains antioxidants that may protect your cells from free radical damage. It even has a soothing effect against skin irritations and sunburn, and may prevent swelling.

A cucumber is about 96 percent water, so it has a hydrating effect as well.

Sweet Potatoes

Sweet potatoes are a flavorful and nutrient-dense substitute for bread. If you’re following a gluten-free diet or not limiting your carbohydrate intake, sweet potatoes are a great option to replace toast or bread in an open-faced sandwich.

One medium-sized sweet potato contains a whopping 438 percent of your daily recommended dose of vitamin A, and 3.8 grams of fiber. They’re also brimming with antioxidants that may help prevent chronic illnesses like cancer and cardiovascular disease.
