An Irish vegetarian stew is the kind of dish that instantly brings comfort, warmth, and satisfaction to the table.

This version of Irish vegetarian stew focuses on rich texture, deep flavor, and generous portions of vegetables.

The result is a thick, satisfying stew that sticks with you long after the last spoonful.
Perfect for a leisurely lunch, this stew pairs beautifully with crusty bread and tastes even better the next day. It’s the kind of recipe you make once and keep coming back to, especially when you want something comforting without being heavy.

Step-by-Step Instructions
Step 1: Prepare the Vegetables
Wash, peel, and chop all vegetables before starting. Keeping the vegetables in chunky pieces is essential for achieving the rustic texture that defines a classic Irish vegetarian stew recipe.
Step 2: Heat the Pot and Add Oil
Place a large heavy-bottomed pot or Dutch oven over medium-high heat. Add the olive oil and allow it to heat until shimmering but not smoking.
Step 3: Sauté the Aromatics
Add the chopped celery and onion to the pot. Cook for about 4 to 5 minutes, stirring occasionally, until the onion becomes translucent and begins to lightly brown. Stir in the minced garlic and cook for another 30 seconds until fragrant.
Step 4: Add the Flour
Sprinkle the flour evenly over the sautéed vegetables. Stir well to coat everything thoroughly. Cook for about 1 minute to eliminate the raw flour taste. This step creates the thick base that gives the stew its signature body.
Step 5: Deglaze with Broth
Slowly pour in 2 cups of vegetable broth while stirring continuously. Scrape the bottom of the pot with a wooden spoon to release any flavorful bits stuck to the base. The mixture will begin to thicken slightly.
Step 6: Build the Stew
Add the remaining vegetables: carrots, parsnips, mushrooms, and potatoes. Stir in the tomato paste, brown sugar, bay leaves, dried thyme, salt, and pepper.
Step 7: Add Remaining Broth
Pour in enough additional vegetable broth to cover the vegetables. Stir well to combine everything evenly.
Step 8: Bring to a Simmer
Increase the heat slightly and bring the stew to a gentle simmer. Once simmering, reduce the heat to medium-low and allow the stew to cook uncovered for 15 to 20 minutes.
Step 9: Adjust Thickness
As the stew cooks, it will naturally thicken. If you prefer a looser consistency, add more vegetable broth, ½ cup at a time, until the stew reaches your desired texture.
Step 10: Check for Doneness
The stew is ready when the potatoes and carrots are fork-tender but still hold their shape. Remove the bay leaves before serving.
Step 11: Taste and Adjust
Taste the stew and adjust seasoning if needed. Add more salt, pepper, or a pinch of sugar to balance flavors.
Step 12: Serve Warm
Ladle the Irish vegetarian stew into bowls and serve hot. This dish is perfect for lunch, especially when paired with crusty bread or a warm roll.
