Vegetable Demi-Glace

Vegetable Demi-Glace

One of the first things you learn in culinary school, or in any professional kitchen worth its salt, is how to make the five classic French “Mother Sauces.” I am a sucker for these sauces, with my favorite being the béchamel. This white sauce is versatile and can be used in various pasta dishes or as a drizzle over roasted vegetables. It also serves as a base for my other favorite sauce, the Mornay, aka the béchamel sauce plus cheese. I love a good vegan fondue. But enough about the white sauces. We are here to talk about the classic brown sauces, and my friends, this is a labor of love.

Sauce Espagnole and demi-glace are both rich brown sauces, but the latter derives from the first. After a Sauce Espagnole has been made, it can easily be used in a 1:1 ratio with brown stock, then reduced by half and finished with wine—resulting in an intensely flavored demi-glace sauce. It can be stirred into soups, stews, and risottos. 

A demi-glace is a brown stock reduced by prolonged simmering combined with an Espagnole sauce or one of the five classic mother sauces of French cuisine. A classic demi-glace is made with veal, but beef and poultry is sometimes used. But we are using a combination of hearty vegetables! The “demi,” meaning half, signifies that the reduced stock (glace) is combined with the Espagnole sauce in a half-and-half ratio. 

You can use whatever you have on hand—provided you combine sweet vegetables with more savory plants for balance. Use too much of the sweet stuff, and the demi could become way too sweet and syrupy.

  • Yield: 1 cup 1x
  • Category: Sauces
  • Method: Reduction
  • Cuisine: French
  • Diet: Vegan



Vegetable Stock:

  • 1 small eggplant, washed and shaved with mandolin
  • 1 celery root, thick sliced
  • 2 leeks, cleaned and sliced (white parts only) 
  • 1 large stalk celery, sliced in half length-wise
  • 2 large carrots, sliced in half length-wise
  • 2 medium beets, peeled and sliced root to stem
  • 1 cup shitake mushrooms (cut mushrooms in half)
  • 1 medium onion, medium slice
  • 1 head garlic, sliced in half (don’t worry about peeling)
  • 1 lemon, washed and sliced in half width-wise 
  • 2 Tbsp tomato paste
  • 1 Tbsp whole peppercorns
  • 6 cups water
  • 1/2 cup dry red wine (sherry or cabernet is preferred)


  1. Toss vegetables and peppercorns in a large bowl with tomato paste, coating well.  Oil bottom of pan—this step is optional but will prevent sticking.   Transfer to a deep hotel pan or other deep (at least 4″ oven safe pan.  Place vegetables in the oven and roast for about 45 minutes to 1 hour. Check your veggies every 20 minutes or so, stirring and rotating as needed to prevent edges from burning. 
  2. After roasting remove from oven.  Add wine, scraping any brown bits. These caramelized morsels of concentrated juice, called the fond—literally, the foundation—will enrich the stock from the bottom of the pan.  Carefully, add 6 cups water to vegetables and return to oven for 30 to 40 minutes.
  3. Strain the stock through a sieve into another pot, pressing the vegetables with the back of a ladle to extract all the juices.
  4. Over high heat, combine 1 part Espagnole to 1 part Vegetable stock, boil for 10 minutes or until reduced by half, stirring occasionally.
  5. Season with salt and pepper.

Vegan Sauce Espagnole

Vegan Sauce Espagnole

Sauce Espagnole is a basic brown sauce, and is one of Auguste Escoffier’s five mother sauces of classic French cooking. Typically made from stock, mirepoix, and tomatoes, and thickened with roux. This easy and basic brown sauce can be used as a base for other French sauces.

According to Alan Davidson, in The Oxford Companion to Food, “The name has nothing to do with Spain, any more than the counterpart term “allemande” has anything to do with Germany. It is generally believed that the terms were chosen because, in French eyes, Germans have blonde hair and Spaniards have brown hair.”

It is also easy to freeze and use as needed! This simple recipe is an adaptation of the great Thomas Keller.


Vegan Sauce Espagnole

  • Author: Stephanie Bosch (Adapted from Thomas Keller)
  • Prep Time: 5
  • Cook Time: 1 hour
  • Total Time: 15 minutes
  • Yield: 4 cups 1x


Basic brown sauce that can be used in a variety of ways. 



  • ¼ cup diced carrots
  • ½ cup diced onions
  • ½ stick unsalted butter
  • Kosher salt
  • ¼ cup all-purpose flour
  • 4 cups hot vegetable stock
  • ¼ cup canned tomato purée
  • 2 large garlic cloves, minced
  • ¼ cup diced celery
  • ¼ teaspoon whole black peppercorns
  • 1 bay leaf



  1. In a heavy-bottom saucepan set over medium heat, cook the carrots and onion in the butter with a pinch of salt, stirring occasionally, until softened, 6 to 7 minutes.
  2. Reduce the heat to low, add the flour, and cook the roux, stirring constantly with a wooden spoon, until golden brown in color, 6 to 10 minutes.
  3. Using a whisk, add the hot stock in a fast stream, whisking constantly to prevent lumps. Add the tomato purée, garlic, celery, peppercorns, and bay leaf.
  4. Bring to a boil, lower heat and simmer, uncovered, stirring often to make sure the bottom doesn’t scorch. Reduced the liquid by about one-third, until sauce coats the back of a spoon, about 35 to 40 minutes.
  5. Pour sauce through a sieve into a bowl, discarding solids.


*Can easily be frozen and thawed when needed.

Mushroom Bolognese

One of my favorite sauces is Bolognese.  It’s simple, delicious, and reminds me of one of my favorite meals growing up.  This meat-free version is made from ground mushrooms and is ready in about 30 minutes.

Mushroom Bolognese


2 (8 oz) packs of cremini mushrooms

1 yellow onion, diced

3 cloves garlic

1 medium-size carrot

1 medium celery rib

2 Tbsp tomato paste

2 Tbsp oil, or water

½ cup red wine

1 tsp basil

1 tsp oregano

1 tsp salt

½ tsp red pepper flakes

½ cup cashew cream

1 tsp rosemary

In a food processor, pulse the onion, carrot, celery, garlic, and mushrooms until finely chopped. In a large pan warmed over medium heat, add oil, or 2 Tbsp water, if not using oil. Add the vegetables, season with basil, oregano, and cook over moderate heat until softened, 20 minutes. Add 1 Tbsp of water, or stock, as needed, to prevent sticking.
Add the wine, salt, and red pepper; and stir. Cook until the wine evaporates.  About 3-4 minutes.

Add the cream, rosemary, and 1/4 cup of grated vegan cheese and simmer for 5 minutes.
At this point, you can either add warm pasta, and 1 cup of water to the sauce and toss, stirring until the pasta is well-coated, or stuff shells and top with remaining creme sauce. Serve.

Cashew Béchamel | Basic White Sauce

This is one of the best béchamel sauces in the whole entire world. Who says you need dairy to make a good sauce?   Not me!  Besides, this is way better than ANY dairy-based sauces I’ve had.  It’s easy and delicious, and makes enough to have leftovers to freeze! Yep, you can freeze this bad boy! What’s better than satisfying a craving for a Creamy Mushroom Alfredo (it’s a “thing” for me) and knowing that all you have to do is sauté some mushrooms while waiting for your pasta to boil! Grocery store Alfredo sauces be damned!

This versatile little sauce can be used in a variety of ways! I use it as a base for corn chowder, in my eggplant lasagna, in a delicious Pasta Con Broccoli, as a drizzle over roasted veggies, and I use it to make a hearty delicious vegetable pot pie! This, my friends, is the real deal.

Step 1: Preparing the Cashews

• 2 cups raw cashews

• 4 to 6 cups warm water

In a medium bowl, soak the cashews in water for 3 to 4 hours to soften. Strain, reserving the cashews and discarding the liquid.

Step 2: Preparing the Sauce

• 1 cup onion, diced
• 1 1/2 cups vegetable stock
• 1/2 cup dry white wine (or substitute stock, if not using wine)
• 2 1/2 tbsp nutritional yeast
• 2 cloves garlic
• 1 tbsp onion granules
• Pinch of freshly grated nutmeg (literally, just a pinch… Too much can alter the flavor)
• Pinch of white pepper (Can use black pepper in a pinch) 😉
• 2 tbsp olive oil (optional if you choose to use oil in this dish)
• 1 tsp sea salt (optional, but I recommend)


First, gather and prepare your mise en place.

If choosing to use oil:

Heat the pan to low to medium heat and add the olive oil. Add the onions and sweat for at least 5-8 minutes to bring out the flavor until translucent. Then continue by adding the garlic and sweat for an additional couple minutes.   Add white wine and reduce until all liquid has evaporated.  (Skip the reduction if not using wine)

*For no oil sauté:
(It is easier to sauté, rather than sweat with no oil. So this process may give the onions a bit of color.)

Heat the pan to medium to high heat. Be sure the pan is heated properly (water test). Add the onions to the dry pan and continue to stir well until the onions begin to turn translucent and stick. Try to keep the onions from browning, adding a little stock or water if needed. You can add the garlic to the onions or add directly into the blender. Remove from heat.

Transfer the cooked onions and garlic into the blender.

To finish the sauce, add the cashews, the remaining vegetable stock, white wine, garlic, nutritional yeast, onion granules, nutmeg, white pepper, and salt (if using). Blend on high speed until smooth. Add more liquid if you choose to have a thinner consistency.

Best Ever Vegan Ranch Dressing

When I began my plant-based journey, one of the first things I needed to find was a good Ranch Dressing.  I know, I know… But I’d be lying if I denied my love for Hidden Valley!  However, consuming pus laden cow’s milk is gross. And artificial ingredients like Calcium Disodium EDTA, and other nasty fake things like maltodextrin, and monosodium glutamate are not even an option.   I had tried many recipes, but was never fully satisfied. So I finally decided to create my own.  This Ranch is delicious and has impressed even my most diehard dairy loving peeps!


  • 1 cup vegan mayo (I like Just Mayo)
  • 2 Tbsp Apple Cider Vinegar (I use Bragg’s with the mother-shaken well)
  • 1 Tbsp Dried Parsley
  • 1 Tbsp Dried Dill
  • 1 tsp Black Pepper
  • ½ tsp Salt
  • ½ tsp Onion Powder
  • ½ tsp Garlic Powder

Mix all ingredients together and use enough water to thin to desired consistency.  Let sit in the fridge for a few hours so the flavors can develop.  Keep refrigerated for up to 3 weeks.
