Heat large skillet over medium heat. Add olive oil and bacon. Cook until bacon is crisp. Using tongs, remove the bacon from the skillet and transfer to the slow cooker.
To the warm skillet, add the beef cubes. Sear on each side until just browned, about 1 minute per side. Transfer the browned beef and any remaining cooking fat to the slow cooker.
To the now-empty skillet, add the tomato paste and red wine. Whisk and gently release any browned bits from the bottom or sides of the pan. Slowly add in the cornstarch slurry, low FODMAP broth, and soy sauce, whisking until smooth. Transfer the liquid to the slow cooker.
To the slow cooker, add the baby potatoes, baby carrots, and thyme. Stir to mix. Cook on low for 6-8 hours, high for 4-5 hours, or until the beef and veggies are tender. Season with salt and pepper to taste.
Serve warm with optional garnishes.
