The full ingredients list and instructions are found in the printable recipe card at the end of this post. I highly recommend reading all the way through for any tips or substitute suggestions, to ensure that you have any specialized ingredients and equipment required and that you understand the steps and timings involved.

I have mentioned before that I have got readers from all over the world, but predominately from the USA and the UK.

However, these two countries (and I’m sure other countries too!) use different words for the same foods. The classic example is [Potato] Chips in the US are what we in the UK call Crisps. Chips for the British are what the Americans would call French Fries.

I know that cuts of beef vary too, not only between the UK and US but also in several other countries. Check out the Wikipedia page for Cuts of Beef to see how different it really is! It has amazed me!





In this recipe, I refer to the US cut sirloin, which in the UK would be rump steak. They both come from the same part of the animal, so it’s just semantics! If you’re in the UK and use sirloin, it’s not going to make a difference – both are great cuts of meat!

This delicious steak recipe doesn’t require a lot of fuss. Just a few simple ingredients and less than 30 minutes are all it takes to whip up a flavor-packed main course your entire family will love!

Ingredients & Equipment Used In This Recipe

While most ingredients can be bought in grocery stores, for your convenience, any specialized or notable ingredients (and equipment) needed for this recipe have been listed below and linked to Amazon or other stores if available online.

It does not include staple ingredients such as oil, salt, and pepper, as you’re likely to have those in your kitchen already. The complete list of ingredients with measurements is found in the recipe card.

  • Protein – Sirloin Steak
  • Dijon Mustard
  • Garlic Powder
  • Italian Seasoningthis recipe uses store-bought Italian Seasoning, but it is so easy to make your own herb mixes, especially if you already have a bunch of herbs and spices in your pantry already. Just mix equal measures of dried basil, oregano, rosemary, parsley, and thyme. You can also add a pinch of garlic granules or powder as well as red chili flakes if you like. Store in an airtight jar and use in recipes as required.

Recipes on The Purple Pumpkin Blog use both cup measurements and/or weighted measurements. American cups and kitchen food scales are handy pieces of equipment to have in your kitchen as it means you’ll be able to make all of the different recipes on my blog. I try to give American, imperial, and metric measurements in my recipes. Please note, you can mix cup measurements with weighted measurements, but never mix imperial (pounds, ounces, pints, etc.,) with metric (kilograms, grams, litres, etc.,).

Ingredients

  • 2 Tbsp extra virgin olive oil
  • 2 Tbsp Dijon mustard
  • 2 tsp Italian seasoning
