Whole Grain Penne with Mushroom Tomato Sauce

Whole grain penne pasta combines with a fresh, light sauce of sautéed mushrooms, cherry tomatoes, and sour cream for a simple yet satisfying vegetarian meal. The earthy nuttiness of whole wheat pasta contrasts beautifully with bright, tangy tomatoes and umami-rich mushrooms, while sour cream adds creamy richness without heaviness. Fresh parsley and shallots provide aromatic depth. This dish appeals to health-conscious home cooks seeking whole grain alternatives and quick weeknight dinners. Serve as a light lunch or dinner, particularly in spring and summer when cherry tomatoes are at their peak. This version prioritizes fresh ingredients and minimal cooking time, avoiding heavy cream or complex techniques while maintaining full flavor through proper sautéing and seasoning.
Ingredients
- 4 ½ oz whole grain penne, raw
- salt, to taste
- 4 ½ oz mushrooms, fresh, cleaned
- 2 ¾ oz cherry tomatoes, fresh
- ⅛ oz parsley, fresh
- ⅓ oz shallots, fresh
- 1 tablespoon olive oil

- ⅛ cups sour cream, 10% fat
Instructions
- 1
Bring salted water to boil in a pot. Add whole grain penne and cook according to package directions until al dente. Drain, reserving some pasta water.
- 2
While pasta cooks, clean mushrooms and halve or quarter depending on size. Wash tomatoes and halve them. Wash parsley, shake dry, and chop finely. Peel shallots and dice small.
- 3
Heat oil in a skillet. Add mushrooms and shallots, sauté for 3-4 minutes, season with salt and pepper.

Mix pasta water with sour cream, parsley, salt, and pepper. Combine penne with tomatoes and mushrooms. Transfer to a plate and pour sour cream sauce over top.
Tips
Reserve pasta water before draining; starchy water emulsifies the sour cream sauce and helps it cling to penne. Start with 1-2 tablespoons and add more if sauce seems too thick.
Sauté mushrooms over medium-high heat without stirring constantly for the first 2 minutes to develop browning and concentrate umami flavors before adding shallots.
Chop parsley just before cooking and stir it in at the end to preserve its bright, fresh flavor and vibrant green color.
Good to Know
Refrigerate leftovers in an airtight container for up to 2 days. Do not freeze, as sour cream separates upon thawing.
Prepare vegetables (mushrooms, tomatoes, shallots, parsley) up to 4 hours ahead. Store separately in refrigerator. Cook pasta and sauce just before serving.
Serve immediately on warmed plates. Pairs well with a green salad, crusty bread, or white wine.
Common Mistakes
Skip sautéing mushrooms adequately to avoid a watery, bland sauce; allow 3-4 minutes for moisture to evaporate and flavor to concentrate.
Avoid overcooking whole grain pasta to prevent mushiness; check al dente at one minute before package time.
Do not mix sour cream directly into hot pasta; temper it with cooled pasta water first to avoid curdling.

FAQ
Can I make this ahead and reheat it?
Cook components separately and store in airtight containers for up to 2 days. Reheat pasta and mushroom mixture gently on stovetop, add fresh sour cream sauce just before serving to avoid separation.
What if I don't have sour cream?
Substitute Greek yogurt, creme fraiche, or heavy cream thinned with pasta water. Greek yogurt adds protein and tanginess. Creme fraiche is more stable when reheated. Avoid low-fat versions which may separate.
Can I use frozen mushrooms?
Fresh mushrooms are preferable for texture and browning, but thawed frozen mushrooms work. Thaw completely and drain excess liquid before sautéing, as frozen varieties release more water and may not brown properly.
