I won’t tell everyone my Buttery Steak Sauce, but keep scrolling if you want the one spoonful that makes steak worth bragging about.

But I am obsessed with my Oh My! Steak Sauce.
I love how it turns a boring steak into something loud and classy. It’s richer than you expect because of buttery notes and a hit of Dijon mustard and a splash of heavy cream.
Not too sweet, just meaty and sharp. I keep it keto friendly so it fits those Keto Sauces nights when I want indulgence and no carbs dragging me down.
Homemade Sauce that actually tastes like a restaurant thing. I hoard this recipe.
Seriously. If you like bold, buttery steak sauce, this is your secret.
Trust me.

Ingredient Quantities
- 4 tbsp unsalted butter, room temp (divided)
- 1 tbsp olive oil
- 2 tbsp finely chopped shallot (about 1 small shallot)
- 2 cloves garlic, minced
- 1/2 cup beef stock, low sodium
- 1 tbsp Dijon mustard
- 1 tbsp gluten free Worcestershire sauce or 1 tbsp coconut aminos
- 1 tsp apple cider vinegar
- 1 tsp granulated erythritol or preferred keto sweetener, optional if you like a touch sweet
- 2 tbsp heavy cream
- 1 tsp soy free tamari, gluten free if you need extra umami (optional)
- 1 tbsp chopped fresh parsley
- 1 tsp chopped fresh thyme or 1/4 tsp dried thyme
- Salt and freshly ground black pepper to taste
How to Make this
1. Pat your cooked steaks dry and set them on a warm plate while you make the sauce, so the pan has all those browned bits to scrape up.
2. Heat 1 tablespoon olive oil and 2 tablespoons room temp unsalted butter in the skillet over medium heat until the butter is foamy but not browned.
3. Add 2 tablespoons finely chopped shallot and cook 1 to 2 minutes until soft and slightly translucent, stirring so it does not burn. Toss in 2 minced garlic cloves and cook 20 to 30 seconds until fragrant.
4. Pour in 1/2 cup low sodium beef stock to deglaze the pan, scraping up all the brown bits with a wooden spoon, those bits are everything for flavor.
5. Stir in 1 tablespoon Dijon mustard, 1 tablespoon gluten free Worcestershire sauce or coconut aminos, 1 teaspoon apple cider vinegar, and 1 teaspoon granulated erythritol if you want a touch of sweet; bring to a gentle simmer.
6. Let the sauce simmer 3 to 5 minutes until it’s reduced slightly and coats the back of a spoon but still loose enough to pour.
7. Lower heat and whisk in 2 tablespoons heavy cream, then stir in the remaining 2 tablespoons room temp butter a little at a time to finish the sauce and give it a silky sheen.
8. If you want extra umami add 1 teaspoon soy free tamari (optional). Fold in 1 tablespoon chopped fresh parsley and 1 teaspoon chopped fresh thyme or 1/4 teaspoon dried thyme. Taste and season with salt and freshly ground black pepper.
9. If you prefer a smooth sauce strain through a fine mesh sieve, otherwise spoon straight from the pan over your steaks. Serve immediately, it tastes best hot.

FAQ
Oh My! Steak Sauce Recipe Substitutions and Variations
- Unsalted butter: use equal amount of ghee or clarified butter for a nuttier taste, or use room temp olive oil for dairy free, though the sauce will be a bit thinner.
- Beef stock: swap with low sodium chicken stock or mushroom stock for a rich umami boost, or dissolve 1 tsp beef bouillon in 1/2 cup hot water if you dont have stock.
- Dijon mustard: use yellow mustard for milder tang or 1 tsp whole grain mustard for texture, or 1 tsp prepared horseradish for extra bite.
- Heavy cream: substitute full fat coconut cream for dairy free, or use half and half if you want it lighter, but reduce heat so it doesn’t split.
Pro Tips
1. Let the pan sit after you take the steaks out so the residual heat keeps everything warm but not so hot the butter burns when you add it. If the skillet is smoking, wipe out a bit with a paper towel and reset the heat lower before adding oil and butter.
2. Use room temp butter and add it in two stages like the recipe says. Cold butter will seize and won’t emulsify into the sauce properly, and if you add it all at once the sauce can separate. Cut the butter into small pieces so it melts quickly and evenly.
3. Don’t skimp on scraping up the brown bits. Deglazing with warm beef stock and giving those fond a good scrape is where most of the flavor is. Tilt the pan so the liquid reaches all the browned areas and use a wooden spoon to loosen stubborn bits.
4. Keep the heat gentle when you finish the sauce. After reducing, lower the flame before whisking in cream and butter. High heat will make the cream split and the butter oil out. If it does start to separate, take it off the heat briefly and whisk vigorously, or add a splash more stock to bring it back together.
