Peel carrot and turnip, and cube the large pieces into cubes, about 1 inch thick. Set aside.
Clean celery stocks and dice them into 1-inch chunks.
Chop the fresh thyme.
Preheat oven to 325 F.
Preheat the Dutch oven on the stove on medium heat with 2 tbsp olive oil and minced garlic.
Once the garlic starts to simmer, place on beef cubes in a single layer (you have to repeat this step 3-4 times), without overlapping to begin the searing process, season the meat with salt and pepper. Add in more olive oil as needed.
Brown each piece of meat for about 2 mins on each side. Once the meat had browned, removed it and add it to a heat-safe bowl. Continue to brown meat until all meat is browned and seasoned.
While the meat is browning, mix together the onion soup mix, beef broth, water, thyme, and corn startch. Whisk everything together until well combined.
Once the meat has browned and is set aside, add the beef broth mixture into the Dutch oven.
Bring the mixture to a boil, whisking continsouly to thicken the liquid mixture as it boils.
After a few minutes of boiling and whisking, turn off the burner. CAREFULLY add in your vegetables and meat using kitchen tongs.
Stir everything together until combined.
Cover with the lid, and place in the oven for 2 hours.
After 2 hours, remove it from the oven and let it rest on the stovetop for 15 minutes.
While the stew is baking, prepare the dry ingredients for the pastry.
In a small mixing bowl blend together, flour, sugar, salt, and baking powder.
Once you are ready to bake your pastry, blend in the butter a little at a time with a fork (it will be crumbly), add in your milk and start blending together.
Gradually add in your water a little at a time until the ingredients come together and you get a sticky dough ball. *You may need a little more or a little less water*
Spray 9 muffin tin holes with spray oil.
Fill each muffin tin ¾ full with batter.
Bake 350 F for 10-12 minutes until the pastry starts to brown.
Serve stew with pastry on top and enjoy!
