🍽 Key ingredients
This key ingredient here is the tri-tip roast. It has to be cut thin to really enhance the sandwich. The fresh ciabatta bread and roasted bell peppers help to bring the sandwich to life!
Tri-tip roast - Cut the roast thinly into ¼-inch pieces.
Ciabatta bread - This bread is perfect for this sandwich because it's hearty and can hold up to all the ingredients.
Provolone cheese - Sliced thin or layered, this cheese is the perfect addition to this sandwich.
Arugula - This peppery green is a great addition to the sandwich and pairs well with the other ingredients.
Horseradish sauce - This creamy sauce really kicks up the flavor of the sandwich. It's made with mustard, horseradish, and sour cream.
Grilled peppers and onion - The sweetness of the bell peppers and the red onions are a great addition to this tender tri-tip sandwich.
You can use any type of bread you like for this sandwich, but a hearty bread like ciabatta is ideal. Other options are Italian or French baguette and Sourdough.
The homemade horseradish sauce has a bit of a kick to it, so if you're not into spicy sauces, you can use other sauces that are sweeter, like BBQ sauce, and garlic aioli, or even a ranch dressing.
You can substitute Provolone for Swiss, Gruyere, or even American cheese.

💭 Cooking tips
Heat your delicious sandwich
If you want your tri-tip sandwich hot so that the meat warms up and the cheese melts, wrap the assembled sandwich in aluminum foil and place it in a preheated oven at 350 degrees Fahrenheit for 10 minutes.
Slice the tri-tip steak thin
For the best tender sandwich, make sure to slice your tri-tip steak as thinly as possible. Thicker pieces are harder to chew through with all the other ingredients.
This tri-tip sandwich is pretty filling as it is, but if you want to add something extra, try some of these variations. Including making the same sandwich with our perfectly cook roast beef recipe or our eye of round roast recipe.
Add chipotle peppers
Adding chipotle peppers to the sandwich will increase the heat considerably and give it a smokey taste. Use vinegared chipotle peppers for a slightly less fiery taste.
Bacon makes everything better, so why not add some to this sandwich? Cook 8 slices of bacon and layer it on top of the tri-tip steak for an added salty and smoked flavor.
For some extra creaminess, add avocado slices to your sandwich. The smooth texture pairs well with the other ingredients. Use 1 large avocado or 2 small ones.
Add caramelized onions
Sweet caramelized onions make a great addition to meaty tri-tip sandwiches. Add 2 tablespoons to each ciabatta loaf on top of the tri-tip. Make them at home or buy them from the grocery-store.
